I just can’t stop looking at Sheldon’s reactions when “Leo” goes off script

"Your parents made the right decison." Lmao sheldon is a straight up savage

Lmao Leo is hilarious and a really good actor

This guy was simply brilliant! They should work him back into the script. Easy to do, as he's supposed to be a teaching assistant.

Imagine waking up on a normal day seeing a stranger eating in your kitchen... "I am Sheldon's cousin Leo" lmao 🤣

All that effort and Leonard still had to suffer through Penny's singing.

12 years later, this episode, and this clip, does not get old. Makes me crack up every time. Leonard's reaction to "cousin Leopold" at 0:18 is priceless!

You gotta admit, Sheldon is a caring friend, he did this all for Leonard. There was nothing for him to gain us this. He even hired an actor just for his friend.

sheldon behind leo disapproving his acting is the best thing of this entire scene

I could never get over how skinny this guy's arms are.

"It was more of a double major actually... theatre and physics... you can guess which one my bourgeois parents pushed me towards."

Funny thing is, the joke towards the end is that they "break character" when they talk about science. But honestly, I would totally buy that Sheldon had a cousin who (growing up surrounded by a military family) went to college for physics, but got lost in drugs halfway through-ending his college experience temporarily and continuing his downward spiral. And, as cousins both interested ins science, they constantly argue about what the cause of his propensity toward self-destructive addiction stems from. The last line, "Your parents made the right decision." would therefore be a particularly mean stab by Sheldon at his cousin's parental issues. Come on, he already tells Raj how his own culture works, would you be at all surprised he'd tell someone why they are an addict?

Penny... You've Been Garthed!

My favourite episode. The lie just kept on escalating and escalating until it became clear that Sheldon would actually have to produce his imaginary cousin Leo. Still shrieked when it happened, though.... and DJ Qualls......perfect! God, I love this show.

4:31 “Your parents made the right decision.” “I cannot work like this!” 🤣

Call Sam and Dean, Garth has been trapped in TV land by Gabriel...

DJ Qualls, the funniest performance by any guest actor ever in this great series. Genius, pure genius.

sheldon´s cousin character was extremely funny he should appear again. he match perfect in the group

Honestly, I wanted "cousin Leo" to show up at Sheldon and Amy's wedding; all clean and sober, fully recovered from the "abuse" he suffered as "a child growing up alone in the Philippines"... 😂😂😂😂😂🤣🤣🤣🤣🤣

I wish they'd had this guy on more. I loved him in "The New Guy"!

11 years later it is still so funny.

pay attention to Sheldon from 3:17 - 3:36 its so hilarious!!

3:07 I love Sheldon's reaction

OMG THIS GUY IS AMAZING. They should totally bring him back!!! And Sheldon's "Jut have fun with it"

His name is DJ Squalls and the reason he's so thin is that he's recovering from Hodgkins Lymphona cancer.

One of my favourite TBBT scenes ever.

Is that GARTH??????

He should have been scripted in more episodes

i love the "au contraire" that he said !!!

This is my second most favorite scene from the series.

"Gin pickled tongue down his adolescent throat " Gets me every single time....lmao

That was my favorite episode

"I was abused in the Philippines-" Oh.

That Sheldon cousin was in Breaking Bad

"Well That's Leo" xDDD

Leo's statement shouldn't be "there was no double blind studies", the statement should have been "there was no randomized controlled trial". And then Sheldon's answer would have been justified "How can there be a RCT, who would be a control group?"

Man I loved this character more than Priya, he's hilarious and I think would have made a great contribution to this show.

one of the most underrated characters on the show, wish we couldve seen him more

The way he raised his head when penny spoke to him

The guy's such a great actor.

I love the way he tells his story to them.

Damn you, Chaplain Horrigan!, gets me everytime... lol.

"When I was 14, I was abused in the Philippines--" oh sht.. that's rare.. WHYYY HEREEEE THOUGHH?

Leo is hilarious, excellent actor

Penny: "After what you told me, I am not surprised!" ... Sheldon's omniscient look at Leonard! 😂😆 FYI: Where I'm from, Leo would actually be the short version of Leonard.

Oh my god, I never realized Garth was in the Big Bang Theory

It would have been hilarious if he’d been at Sheldon’s wedding in character 🤣🤣🤣

I love how they start argueing infront of penny

After watching Man in the High Castle religiously for over a year it's weird to see DJ in this role

Leonard still got screwed lol

i wish they had kept him as an occasional guest, like stuart or kripky. i love him.

This is such a great moment. I rewatch this clip often!

Honestly; this is my ultimate Favorite episode of TBBT. That guy can act xD Wish he comes back as a recurring cast

Leonard: Who are you? Leo: I am Sheldon's cousin Leo Leonard: oh god

One of the best episodes!

I liked how Sheldon was looking in the background when 'Leopold' was talking about the Navy chaplain.

see the eyes when leo is explaning the philppiness story

Legend has it that Leonard never told a lie again

This is my favourite episode 😂

This was one of the best episodes hahah

one of the best episodes.

Had Leo been given few more episodes, he would have surpassed all those 'science dudes'. 😂 And Penny. Well Penny would be with Leo. And not Leonard 🤣

Great ep! very funny

Sheldons cousin Leo story is funny

That guy was amazing 😂😂

At first I thought he looked familiar then remembered he was on criminal minds

Cousin Leo and Barry Kripke are my favs of this show.

We like Pizza. Joey likes pizza. Now get out and wait in the hall

omg it's Garth from supernatural!!!

You could say that Sheldon has been...............FIZZLED!

Sheldon’s 3:07 is unbelievable, best face ever!

This guy appeared in breaking bad as an undecover cop

Garth from Supernatural!!!

You have officially been Garthed!

A complex lies that makes you want to tell the truth instead 😂😂

GARTH!! haha. Anyway he's so adorable haha Sheldon's cousin Leo should come back for more episodes.

Awesome another SPN fan watching BBT clips! ;)

they should add "cousin leo" more often xD

i love leonard's expression !

This episode was the first time I realised how effed up Sheldon's cerebrum is.

Leo is amazing!

Garth what are you doing there? Garth you're in the wrong show.

I really miss these seasons of TBBT !

One of the most iconic scenes of BBT!

I agree! He's funny as hell! LOL!

YOU HAVE BEEN GARTHED!!!!!!!!!!!!

To be far, dealing with Sheldon is like dealing with a pissy Dean.

I knew what episode was that about when I saw the image and the thumbnail 😂😂😂🤣🤣

Ha! You're right. It makes him physically perfect for the part!

Absolute gold. Peak big bang theory.

I cannot work like this...LOL...

one of my fav with cousin Leo.. so FUNNY

just one episode and this guy stood out with his acting skills, brilliant performance skinny guy

This is one of the best acting (by Leo) and even better re-acting (by Sheldon) I have ever seen..I mean just see when he says, DAMN YOU CHAPLIN HARRIGAN...

Wonderful performance Toby!

My favourite tbbt scene

DJ Qualls needs to be a regular on this show!

Lol , D.J. Qualls is funny as hell

How could there be a double blind study? Who would be the control group? I love that mini argument near the end

Dj Qualls is a badass actor.
