The cast of CBS’s The Big Bang Theory, including Kaley Cuoco, Johnny Galecki, Jim Parsons, Simon Helberg, Kunal Nayyar, Melissa Rauch, and Mayim Bialik got together last night (December 15th) at the California Science Center in Los Angeles to celebrate the sitcom’s 100th episode.

“We’ve been watching over this year how in small ways the relationship was talking at them,” executive producer Chuck Lorre told TVLine of Penny and Leonard’s relationship.  “The friendship is going well, but then we throw in a moment where she was drunk and [said] she regretted breaking up with him. So, although it is a little risky, it felt like the right thing to do, to explore Leonard and Penny again in the 100th episode.”
