Top 30 Memorable The Big Bang Theory Guest Stars

[@joermnyc]

Teller as Amy’s dad was also hilarious. And yes he can talk!

[@paul16451]

Yes, he has no issues with talking. Even in his early days he would usually come out at the end of the show to speak with audiences. He also did lots of interviews before this appearance, saying his perceived silence is nothing more than his stage character.

[@jaredlowder5248]

He even spoke on Fool Us during their signature knife trick. I honestly believe it was to stretch the trick out to fill time

[@paul16451]

@jaredlowder5248 I think there was another time on that show when he yelled out "F*ck No!" when asked something, although I don't remember the context. Although the first word was bleeped out of course.

[@livetoforgive8691]

He can sing too. Mask singer.

[@frankbrodie5168]

"Live long and suck it!" is the greatest line in TTBT for me. And I love pretty much everything about the show.

[@thetattedpharmacist3215]

Also the fact that no one on set knew he was going to wear the Star Trek uniform. Made that whole scene so much better knowing that afterwards 😂

[@selysia]

My favourite is in fact Wil Wheaton. I love every single appearance of him on the show, him playing an "evil" version of himself was such a good idea 😁

[@4Just1Girl]

My Fave legendary lines were "Live long and suck it!) as well as when the guys were going to see Raider's of the lost Ark (with 21 extra minutes at the end)and Sheldon got extra cranky and threw a hissy fit when the guy at the door (Actor/Comedian, Eric Andre -- who played Max's Boyfriend Deacon/Deke on 2 broke girls) allowed Wil Weaton to go right in to the theater, and Sheldon got his 'tuff' side to meanly ask, when they are NOT allowed inside--" What makes You think You can decide Who's allowed in and who to keep out?' and Andre' exclaims loudly a statement he heard Sheldon say in line before, He looks Sheldon straight in the eye, and strongly gets in Sheldon' face, "... Because, I'm the Perfunctory with the clipboard. Bitsh!" ( LOVED That Sheldon Got put in his place!) I had to look up the New word I learned and discovered it's actually a very Insulting and Highly rude, put down someone uses to describe another person as being Rude, Obnoxious, has no "F's to give. is thoughtless, doesn't give a care about anything, or anyone, ). My thoughts are gee, I can count on 2 hands a lot of people Sheldon has always been rude, and obnoxious, and Condescending. to who seriously Believes HE (Sheldon) has BEEN this way since he was in the 1st grade! reminds me of Penny's early fights with Sheldon when she first met him, and at the Cheesecake factory when SHE told Sheldon the business now had a new policy, of..."No Shirt.no Shoes,...No Sheldon!" then Raj and Howard lean in to each other where Howard whispers, "I bet we could sell people All over Pasadena...with that."

[@stephendaurie9344]

Although not mentioned and only making one brief appearance, Howie Mandel was one of my favorites

[@KakiOlsenCreative]

That made me laugh so much.

[@badbiker666]

I must agree with your comment that Katee Sackhoff and George Takei had incredible chemistry when they appeared in Howard's fantasies. They were both, individually, awesome in that episode as well. I don't know much about her, except for her role on Battlestar Galactica, but I was impressed with how well she handled the TBBT part. George Takei , on the other hand, is one of my all time favorites! Would I like to see them together in something again? Oh HELL yes!!

[@Eva_H]

Katee was also in season eight of 24 as a love interest for Freddie Prinze Junior (ironically he would go onto voice Kanan Jarrus Star Wars rebels) and Star Wars TCW S3-S7, two episodes of Star Wars rebels and reoccurring in the Mandalorian as Bo Katan Kryse.

[@yxeaviationphotog]

That whole scene with George Takei and Katee Sackoff will always be my favorite.

[@joshuampinganjira97]

Regina King should be on this list. She was great as Human resources manager at the University

[@lw3269]

Yes! Second only to Bob Newhart.

[@francisbtube]

I disagree so much. She says the most annoying line I have ever heard on Television from any character. When she said to Sheldon Cooper, “I don’t understand what that means, but I’m going to go ahead and tell you, you can’t say that”… I just had to shake my head and metaphorically weep. It’s a line that’s indicative of everything wrong with the culture we now live in. For two reasons a) the ridiculousness of taking a stand on something one doesn’t understand and b) the fact that we now live in a society where we are told what we can say and what we can’t. The writer George Orwell in his book 1984 predicted this kind of behavior in the future when he published his novel in June 1949. That’s why I found it not funny but profoundly disturbing this would be written into a sitcom and have the studio audience be encouraged to laugh about it. This isn’t a comment about the show that I still am watching in reruns or King who is talented and accomplished, but her character just bugged the heck out of me every time she made an appearance. Anyway mate just IMHO, no offense meant. Have a great day!
