100 episodes already?? That's a huge accomplishment for a TV show!
The cast of The Big Bang Theory celebrated their 100th episode with a poppin' party at the California Science Center in El Lay.
Stars Johnny Galecki, Jim Parsons, Kaley Cuoco, Simon Helberg, Kunal Nayyer, Mayim Bialik, Melissa Rauch, and executive producer Chuck Lorre rocked out with the Barenaked Ladies, who performed at the party, and a huge cake, which they all took turns cutting.
Looks like fun! Congrats on the huge milestone!
