Did anyone notice that Professor Proton sat in Sheldon's spot and Sheldon actually didn't comment about it? It's a miracle!!!

Bob Newhart as Professor Proton is genuinely one of the best comedic performances I've ever seen

Rest in peace, Mr. Newhart. You were hilarious for more than 6 decades!!!

Professor Proton's patience with Penny is adorable. Such a gentleman

"Any chance we can plug it into the potato?". ... "ⁿᵒ"

Oh Professor Proton, you only apear in some chapters and stole the show!. Even saying "No" you're Awsome!!!

Penny with that potato in the end.. Omg.. *died laughing*

"What do you two talk about?" _Leonard does not want to admit how ever since he met her, he just wants to give a Big Bang._

I liked his politeness when Penny asked to help with Potato.. And he says: "No"

I feel like they didn't give Professor Proton a script and just said go for it. He is hilarious😂😂😂😂

Bob Newhart's stutter really helps with his character. I mean I feel bad that he has it but it's always helped make him funnier throughout his career because he adds that into all his characters.

He really did steal the show. The way he delivers his lines is fantastic 😃

And so art becomes reality. Rest in power, Bob.😢

Congrats Bob for finally winning your Emmy! Too bad it took this long but what a fun role to win it for.

"the puppeteer who did Gino, also, did my wife" LMAO

He sat on Sheldon's spot n didn't say anything That speaks volumes considering how much Sheldon loves his spot

Penny's question about the potato solving the world's energy crisis was actually valid if you don't understand how it works

I have a bracelet with my address on it. That kills me every time.

Bob Newhart is a master of his craft. Even at the age of 87, his ability to stay on timing and voice control is amazing. While I am sure that other actors could have completed this role, Bob Newhart was the perfect actor!

When Sheldon and Leonard are telling him that he was an inspiration for their pursuit of science is, to me, one of the best scenes in the show.

the fact that Sheldon, an actual world class physicist in this series universe, told prof Protons how much he meant to him and he is the reason Sheldon pursuits science must have lift a huge stress in him. I wish Sheldon would include him in his Nobel speech, hearing that he inspired a Nobel laureates would definitely let him in peace even just a bit.

"Do you remember that?" "I'll give you a hint. I have a bracelet with my OWN address on it." Lol

I really like TBBT. But anything with Bob Newhart in it is always going to be very special. Very very few people have his gift of comic timing - he's just a joy to watch.

The writers on this show are AMAZINGLY!!! And the actors really deliver...Love this show!

I love penny's enthusiasms here ...like an eager child she wants to know science behind these... Also that was emtional when sheldon and Leonard explains professor proton how he inspired a whole young generation scientist...

Never laughed so hard about someones „No“... epic 😂🤣

Bob Newhart, with that deadpan face, "No." Cracked me up! Hilarious!

Penny's reactions to the science experiments (the egg and the potato) are perhaps one of the funniest scenes in the entire show... Her reaction when Dr. Proton mentioned he was going to power a clock with the potato, she was like "SHUT UP, YOU CAN DO THAT??" 😂😂😂😂😂😂

4:06 i think the very soft no is just perfectly delivered. It had me rolling with laughter.

When you realise that when we are older we will probably see Mathew Perry doing his sarcastic bits on shows like this one

every "No" from professor proton is just priceless

The difference between an actor reading his comedic lines and an actual comedian with perfect timing and decades of experience. Newhart is the best.

Nobody can deliver a "NO" like Bob Newhart. He is the one comedian that can make me laugh without being dirty. Truly one of the best comics of all time.

One of the best minor characters. Every line delivered with so much sass

Penny inquiring if they can plug the pacemaker into the patato is friggin hilarious!!!!!

Penny is so cute in this episode and hilarious.

HAHAHA, I love the way Sheldon is looking at Penny in the end, when she proposes to use the potato to plug into his pacemaker xD his expression is like "you idiot, can´t you just be quiet xD"

I love Penny! Arthur too when he said “The guy that did the puppet .. Did my wife too!!” 😂

Penny was so sweet in this scene.

Years later and I still laugh hysterically at that" also did my wife" joke.Such incredible line delivery.

Professor Proton's comedic timing is impeccable.

His delivery is just perfect, he just waits for the right moment.... the right pace, not too hasty...

Bob Newhart is so hilarious in this episode. Great scenes!!!! Laughed out loud!!!!!!

2:26 "What do u 2 talk about?"... Sheldon keeps asking same question.....🤣🤣🤣🤣

I laughed hard when he said I'll give you a clue,I have a bracelet with my own address written on it🤣🤣

2:21 comedy GOLD - what do you two talk about :D silly girl!

Leonard was so embarrassed for penny🤣🤣

2:22 I like how Professor Proton asks Leonard "what do you two talk about in this" scene

"I could've wound up as a hobo...or a surgeon!" Killed me😂😂

Impeccable timing and that classic stammer. We will miss you, Bob.

Playing dumb is so difficult.. she nailed it..

"I'll give you a hint: I've got a bracelet with my own address on it."

Sheldon disapproving Penny's idea to power the pacemaker with potato was hilarious 🤣

I Love Bob Newhart and the character he plays. Apparently Sheldon does too. The writers must bring him back this season! This was hilarious.

This guy's a genius. His acted awkwardness was gold....

Bob Newhart was brilliant,the comedy timing pure genius,this sketch really makes me laugh..

That professor Proton is gold 🤣🤣🤣🤣🤣🤣🤣🤣 His answers are always killing me. I literally died at the bracelet thing🤣🤣

This is pure comedy gold. Bob Newhart didn't say much for his funniest parts but his comedic timing is so good he doesn't have to say much to get huge laughs. The "no" at the end had tears coming from my eyes as I laughed but it was just one word and I knew it was coming, but still made me laugh out loud, he is just that good.

Bob Newhart’s performance in TBBT is absolutely Fantastic! Every time he’s in an episode... I always smile 🙂 Not to mention the writing is complete Genius... it just makes it even better

I have loved Bob Newhart pretty much my entire life, and I still couldn't believe how funny he was in this clip. Literally laughing out loud at his comments.

Absolutely hysterically funny! Bringing in Bob Newhart made the best sitcom on TV even better and executed by both the writers and actors immaculately.

I've said it before and I'll say it again: episodes of the Big Bang Theory that included Bob Newhart are some of the funniest shit ever. Fun Fact: he won his one and only Emmy for this episode.

“I have a bracelet with my own address on it….” Omg 😂😂😂😂😂😂😂

I feel like if Penny has seen his show growing up she might have had a different life.

3 minutes of the most funny dialogue I have heard in years.

I like it when Sheldon says, '' I have to say something'', and then everything goes well. Sheldon is not just a genius he is adorable too. Kudos to the people behind this...

The screenwriters were particularly brilliant in this episode

"wouldn't that solve the world energy crisis" LOL yeah ok, lets have everything powered with potatoes. Machines, cars, devices, etc. haha

I don't think I can think of any other comedian with his timing and delivery.

Penny's reaction to the clock is actually beautiful. a lay person just became instantly fascinated with the wonders of science. In Prof Protons last bday performance. he genuinely inspired someone to science. "Any chance we can plug it into the potato?" may sound silly, but she's thinking and applying. that's something.

...to bring this guy into the show was a MASTERPIECE! :) ...what you call a "stroke of genius"! :D (- no irony intended!) :) ...

Newhart's delivery is so perfect.

I found this episode touching, Sheldon´s reaction towards Professor Proton is very cute, we can see how much appreciation he has for someone who lows downs his work, but the speech Leonard and Sheldo gave to him about how much young kids were motivated leading them to be what they are now, like Sheldon has some much value in life, he is a true life hero, not even thos comic super heroes books they geek about. This episode is beuatiful.

"SHUT...UP! U can do that???" Lmaoo Penny was so cute

prof proton validation when Sheldon said hobo or surgeon killed me, prof proton is a physicist true and true.

All this time later this still makes me laugh. Mr. Newhart's pause before saying NO is perfect

All the actors on the show said that it was a true honor to work with Bob - his sense of comedic timing is world-class. I bet they felt like they were back in acting school, and he was the teacher!

Bob Newhart was awesome, in this episode. He was perfect for the part! A comedy genius (and best friend of Don Rickles)!

Her question about the potato~pace maker and his response, gets me every time.

What I love most about TBBT is that the guys love their job and they are all so passionate about it.... just as passionate they are about comic books. The disregard Sheldon holds for all other professions is something that is so admirable.

Professor Proton to Leonard: "What do you two talk about?" Brilliant. 😂

But Penny seems to really excited about those experiments. If she would've watched that show as kids she probably had became scientist too

R.I.P Bob Newhart Great Comedy Legend 3x Grammy Winner Emmy Winner Golden Globe Winner We will be miss 😇😇🙏

(After Penny asked her question) Prof. Proton (to Leonard): " What do you two talk about" WHUTTT!😂😂😂

I'd love to see the bloopers for this scene. This clip had me laughing harder than any other big bang clip i've seen recently.

I love it when Sheldon shakes his head at Penny. It’s like he’s saying “You should be ashamed”. And Penny’s like “I know”

"no" was the funniest no ever 😂

a thousand-page-long PhD compressed in one word: "No." :D

This scene still cracks me up to this day. XD

Probably one of the best episodes ever!!!!!!!

Professor Proton sits on Sheldon’s spot and he doesn’t mind it, that tells you how much Sheldon loves that man. 😢

"Any chance can we plug it into the potato?" 😂😂😂

the timing of the punchlines were perfect! I love this show!

*A generation of young engineers are standing on shouldlers of Iron Man*

Bob is a master of understated comedic timing.

That "NO" was awesome!!! 😂

"You're...the reason I've stayed this long"...perfect line perfect delivery

Kaley's response 'shut up' is so funny and also funny is the way she was able to have a rather bewildered and confused look on her pretty face.

Interesting that Sheldon keeps calling him "MISTER" Jeffries when Sheldon knows that he has a doctorate. Sheldon should be calling DOCTOR Jeffries.

I just finished watching this episode, it was magic.
