The fact that Koko tickled Robin cause tickling makes her laugh, she wanted to make him laugh too. A gorilla wanted to make human genuinely happy out of her own will, that just blows my mind. They're so damn smart, they don't belong in zoos

Hope they're having a good laugh together now wherever they are

Koko must’ve sensed Robin’s true feelings and wanted to make him laugh. Both were sweet and genuine beings

I truly believe this was one of Robin's most favorite life memories he got to experience. What a connection and interaction between these two.

Not sure if I'm here for Koko or Robin Williams

I like to think that Robin and Koko are still tickling each other

Maybe Robin and Koko are up there in heaven tickling each other right now.A friendship that lasts forever.

Koko taking his glasses and walking into the room with them still on is so adorable 😭

Whatever pain Robin was feeling that day, Koko made it go away. Rip to them both 💘

A tender, loving, funny and hairy being... and Koko was pretty cool too.

Words can't describe how much happyness this video gave me

This really makes me choke up, almost in tears watching this again. R.I.P Robin & Koko you both certainly made the world a better place.

"We shared something extraordinary" Yes, those hairy ass arms Jokes aside, we miss you robin, we really really do.

When a Gorilla an inch away asks you to tickle, *you better tickle*

With all the struggles Robin had, it's wonderful to see this glee on his face, like it's from deep in his soul. We miss you ❤

This is really special because this is one of the few times Robin seemed comfortable just being him. No goofy noises or imitations. This is how you know he is at a very special place in his heart. I only wish he could have stayed there more. The world will never get over him. ❤️

She really finessed his glasses and was like " need to cop me a pair of these "

“Heard a joke once: Man goes to doctor. Says he's depressed. Says life seems harsh and cruel. Says he feels all alone in a threatening world where what lies ahead is vague and uncertain. Doctor says, "Treatment is simple. Great clown Pagliacci is in town tonight. Go and see him. That should pick you up." Man bursts into tears. Says, "But doctor...I am Pagliacci.” -Alan Moore. RIP Rob

Robin needed much more Koko in his life. We probably all do.

Two peaceful beings that brought so much happiness to the world.

she's like "i like this guy, he's funny." We all did, Koko... We all did...

I hope they both are resting in peace.

I love that he didn't treat her like an animal. He was attentive and respected her as a being. Love him even more! ❤

you can tell Robin really enjoyed himself and got lost in the moment!

Seeing how a gorilla and a human can so easily connect and form a special bond is so heartwarming. I hope Robin is giving koko tickles in heaven

Robin Williams was such an incredibly talented man. From his stand up comedy to his serious performance as a psychologist in good will hunting his range was impressive. He will forever be missed. He surely seemed to be truly enjoying this visit with KOKO.

RIP Robin and Koko hope you two are making everyone laugh in heaven ❤❤❤😊

It was so heartwarming seeing Robin Williams smile and laugh, because at times he seemed to have sadness in his eyes. Rip Robin Williams!

Why am I crying? Maybe because they're both gone. Ugh.

I've seen the full version of Robin and Koko's time together. It's the most precious video I think I've ever seen. I'm imagining them together in Heaven tickling each other and laughing outrageously. Two gentle souls. RIP both of you!

Man, I can't believe YT took so long to recommend me this video. I mean, how can you not love it right from the beginning? It's Robin Williams interacting with a super gentle and smart gorilla. It's the kind of thing that you'll never see again in your life. What a precious video, I couldn't help but smile the whole time ❤️

Not satisfied with just making humans laugh, Robin Williams became the first comedian to bring joy to gorillas... Now that's a master of the comedic craft right there.

Can you imagine being hugged , tickled and communicating with a gorilla? Must be incredible.

Robin Williams has made millions of people laugh, and with watching this, I don't think I've ever seen him laugh like he is in this video. Amazing man.

A phenomenal interaction between Koko and Robin. It must have so warmed his heart. 💕😢💕

This is the purest thing I’ve ever seen

when she wore the glasses, she looked like Winston from overwatch lol

Watching two of the very best of us together. Can't watch without crying.

It’s so beautiful seeing that gorilla smile with a human so wholesome

Koko shows more human qualities than most people out there. Such a gentle angel may she rest in peace.

I read that Koko, when she first saw glasses, called them eye hats.

Two national treasures.

This video breaks my heart a little, but I always come back to watch it again

Koko the Gorilla was truly a genius. She is one of the few animals ever to shatter the barrier between human communication with different species and its so amazing.

"They had a lot to discuss!" Tickles each other the entire time lol

We need more people in Hollywood like Robin, such a big heart

Robin seemed like such a gentle soul. So sad to see him go. I truly hope that he found peace.

When I see how happy he is here tears fall on my face.May he rest in peacexx

The last scene of Robin being held in Koko’s arms was one of the most pure things I’ve ever seen. So beautiful.

I so miss Robin Williams. The only person he couldn’t make smile was himself. RIP Robin/Koko

He truly understood people, I feel like nobody really understood him

My dear God, my heart still beats. It is so hard for me to accept their passing I knew about Robin but not Koko. I am in tears over such friendship as this. Sweetest thing to see and so precious. 💐🕯️😔

RIP Robin and Koko. You both made the world a better place your spirits live on.

Robin Williams was a wonderful human being.

If only Koko could have been there the day Robin was so sad he decided to leave. She could have cheered him up. Animals like this and dogs and cats and birds are God's gift to us.

Two incredible lights, that illuminated love and friendship. The world is a better place, being touched by them.

This is what KZfaq is for, soul-healing. Rest in peace you two.

No one is gonna comment how gangster the Gorilla looked walking dem glasses like a professor

If there's one video that's both stunning and wholesome, it's this one. The only bitter note here is knowing that neither of the two is with us anymore.

The silent bond Koko and Robin shared is amazing to see but also heartbreaking now. Knowing Robin was suffering so much emotionally, it brings tears to the eyes. ❤

They're both very special and the world looks grimmer without them.

The world is a bit less bright without these two amazing beings. We miss you, Koko and Robin.😢

God I miss Robin Williams. Such a gentle and beautiful soul. The world is so much less without him.

Two treasures gone from this earth . We miss you both . ✌️

This video is an absolute gem. Two of the most beautiful beings ever having fun together. Thank you for preserving this very special occasion.

The passing of Robin Williams was one of the only times I felt deeply saddened for someone I never met.

You can see the connection between them just by looking at Robin's face. As someone who lives with depression, it's hard sometimes to feel a genuine connection with someone without paranoia or doubt. But in this moment, I think Robin genuinely felt at peace because Koko was just so honest in her actions. It's truly a beautiful thing. Whatever he was going through at the time, Koko made him forget. I'm sure both of them are having a great old time wherever they are. RIP to these beautiful individuals.

This is the only time I've not seen Robin 100 mph. Such undivided attention. So beautiful. If animals can sense a good soul, this is all I need to know about Robin Williams.

Koko the Gorilla passed in her sleep last night. She was 46, which is a ripe old age for a gorilla. I sincerely hope that in whatever afterlife there is that Robin Williams is waiting for his friend Koko.

I was smiling and enjoying the video when it occurred to me that they were both gone now.... and then in a second I completely broke down again because I was originally watching to feel better.... because my son died a month ago. Damn... death is so fuc*ing hard. RIP Koko and Robin and my Chaz.

Adored Robin Williams and so did Koko! That. Is the happiest I have ever seen Robin .

When you're having a tickle fight with someone who could easily rip off both your arms and use them as drum sticks. What an amazing, gentle creature.

Goodbye Koko...Be sure to say hi to Robin Williams on your way in.

I had no idea Koko died 😢 Breaks my heart to hear that! What an amazing experience though for RW. I would do just about anything to have this experience myself. Beautiful interaction ❤

Was having a bad day and decided to watch this again, I feel better. Pure Goodness.

You can see the absolute love and wonder in Robin’s eyes I miss them both

This one made me cry, tears of joy and sadness. I was blessed because I worked on 5 of Robin's films. One day I asked him what it was like to meet Koko. A huge smile came over his face. "Amazing. It changed my consciousness, forever." I could see that he was in love with Koko. Whenever his children were on set, he had a discernable 'sparkle' in his eyes. And when he talked about her he had that same twinkle in his eyes - which also 'smiled.' He said that she saw all that hair all over his body and must have thought he was at least part simian. Because his body hair was 'an issue' and one that he joked about on occasion. I laughed. Not just because almost everything that he ever said was funny in and of itself but because on one film in particular (Father's Day) we were filming in downtown Reno, NV, and it was getting pretty hot out and he was across the street meeting and greeting all of his fans who got the usual show - he absolutely LOVED entertaining his fans whenever he got the chance. Being on the crew and behind the scenes was at times riotous. The lines that he improved and that eventually wound up on the cutting room floor were always far funnier than the scripted lines which wound up on the film. When he was done he had them all laughing and smiling and came over to where I was at, and said, "Damn its getting hot" and then proceeded to take off his shirt. I noticed that quite a few of the people looked almost shocked, stunned even. We were within earshot of the onlookers so I said, "Wow. Thats a really nice sweater youre wearing Robin, where'd you get it?" And as usual, he delivered a line without a moment's hesitation (he was so quick on his feet), he said, "You like it? I got it for my birthday." The crowd cracked up. A little known aspect of Robin's career, which I saw so many times on set, was how he would have lunch with Make-a-Wish children, who were diagnosed with terminal conditions and just wanted to meet this wonderful person they enjoyed watching on TV or in a movie - usually Aladdin - and unlike every other 'star' instead of going to his trailer, he would pour his heart out to these kids for an hour, and give them shirts and hats and signed posters, and laughter, and maybe even hope. He was the nicest person I ever met in the film industry and maybe even in my life. I had a genuine respect and love for that man. I was so happy to see this video of their meeting for the first time after all these years later. Bless both their Souls. Knowing Robin was amazing, and I am saddened that these two great Souls are gone, but both of these 'Angels' changed the consciousness of the world and have returned to the place from whence they came. I miss him. But he earned his ticket back home and I hope he has healed all the hurt that he kept hidden in his heart, while he was busy making everyone else laugh. I miss Koko too. Just the idea of what Penny and her did to change peoples awareness regarding the true nature of animals and their beautiful spirits and their heartfelt emotions, and their innate understanding of human nature, and their ability to forgive us and our ignorance of all that they are, has rung a bell for the whole world (and especially within me) that cant be unrung. Love eternal to you two hairy friends. 🙂🙏

That is completely Beautiful. Two huge stars sharing hugs and laughs. Sadly gone but never forgotten ❤️❤️.

i've been really sad lately but this made me smile... koko and robin deserve to rest in peace; they brought so much joy to the world and they'll never be forgotten

I feel that Koko understood Robin better than any human in these moments.

They’re now with each other in peace

You are sorely missed Robin … You made our lives shine brighter with your infectious humour and voices Sorry we did not see or recognise the darkness behind the Mask you wore ❤️❤️❤️❤️

When she put the glasses on it's like she's trying to make him laugh too, she's so damn smart and cute

He was so gentle and kind with her. Still can't believe he's gone

So happy to see such joy and awe in Robin’s eyes, for he brought so much joy into the world RIP Mork n Koko

I don't think Robin knew just how much he was loved by so many and it was more than just his acting that people loved. It was just him!

The world misses both Robin and Koko!

Robin: *tickles* Koko: *laughs shyly and knocks him through the wall*

Two of the purest souls to have graced our world and we are all better for it. Both equally missed and loved.

Wonderful moments, why on earth do people with such incredible talent suffer so much and leave us so soon. Very much missed.

This Earth has only gotten bleaker without them.

What could be more beautiful in this world than seeing love,peace and harmony

That was genuine happiness❤

This world could be such a peaceful place...

Koko picked up on his depression, that's why the attempt to articulate tickle, to bring him joy

Wonderful to see the interaction. RIP Robin you are sadly missed.

Robin was a loss to mankind, i and many more will miss him tremendously.

I love how Koko smiled when Robin tickled Koko. 😄😃

The world could use a little Robin Williams humor right now. It’s a duller place without him.

What an experience to meet Koko. 💙💙💙
