This Game Proves That The Big Bang Theory Stars Really Just Play Themselves on TV

Mayim Bialik is the Amy and Kaley Cuoco is the Penny

Liam Mathews

The Big Bang Theory's farewell tour is starting. The long-running sitcom will end in the spring, and the cast stopped by Ellen for Thursday's episode to talk about working on their final stretch of episodes (it's just starting to hit them that the show they've been on for 12 years is coming to an end) but mostly to play a trivia game called "The Big Bang."

The game is simple: quickly answer trivia questions while a balloon fills up with air. You buzz in, the balloon stops filling. You get an answer wrong, the balloon keeps filling. The team whose balloon pops loses. Ellen DeGeneres split the cast into girls (Kaley Cuoco, Mayim Bialik and Melissa Rauch) and boys (Jim Parsons, Johnny Galecki, Simon Helberg and Kunal Nayyar). And what we learned is that, in a trivia setting, Mayim Bialik as a lot in common with her character, Amy, while Kaley Cuoco shares some traits with her character, Penny.

For instance, Bialik, who plays a brilliant scientist on the show, knew answers to most of the questions off the rip. Cuoco, who doesn't play a brilliant scientist, thought the national language of the Bahamas is "Bahamian." (I guess she hasn't watched the Fyre Fest documentaries, because if she had, she would know Bahamian people speak English.)

For Ellen's full interview with the Big Bang folks, tune in this afternoon (check your local listings).

The Big Bang Theory airs Thursdays at 8/7c on CBS. It can be streamed on CBS All Access.
