    Teller as Amy’s dad was also hilarious. And yes he can talk!
  • @frankbrodie5168
    "Live long and suck it!" is the greatest line in TTBT for me. And I love pretty much everything about the show.
  • @JuJuBeeJulez
    “Don’t make me climb over this counter” Octavia was not about to play with him 😂
  • @herdzskyj5477
    My favourite was Kathy Bates as Amy's mom and Christine Baranski as Leonard's mom.
  • @RayBaird-sy2ok
    Buzz Aldrin wasn't the only astronaut on the show. Remember Michael Massimino? He was hilarious!
  • Glad you told me who Rick Fox was. My favourites were James Earl Jones and Carrie Fisher bloody hilarious
  • Network: How many Star Trek legends cameos do you want in the show? Chuck Lorre: Yes
  • @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!!
  • @luedanger561
    My favorite "cameo" is Penny's mom who is played by actress Katey Sagal. I absolutely love Katey. She's been in a bunch of my favorite sitcoms and series
  • @lh412
    I love that Octavia Spencer guest stared on Young Sheldon too.
  • I really enjoyed Kathy Bates and Teller as Amy's parents. Who knew Teller could speak!
  • Regina King should be on this list. She was great as Human resources manager at the University
  • Kinda cool that TBBT have guest stars that have some scenes of nerdiness, either through their occupation in the science world or the pop culture world.
  • @miguelsilva3867
    I actually thought that Wil Wheaton and Bob Newhart should have been top 5 since they made the most cameos and the most memorable.
  • @trinaq
    I love that none of the characters recognised Neil Gaiman, just writing him off as a random guy in the comic book store. 😂
  • @amitmeir8109
    Not even an honourable mention to Sean Astin, Kathy Bates, Teller, Katey Sagal or Neil Gaiman?
  • All of these celebrity cameos were awesome❤️ my personal favourites were Mark Hamill James Earl Jones, Carrie Fisher and Stan Lee and Will Wheaton 😄
