'Big Bang Theory' cast surprises audience with 'Call Me Maybe' flash mob

Bazinga! On Oct. 23, the cast and crew of "The Big Bang Theory" treated its live audience to quite a treat: a flash mob that kicked off with Carly Rae Jepsen's hit "Call Me Maybe."

The surprise performance began as the cast was seated in Leonard (Johnny Galecki) and Sheldon's (Jim Parsons) living room. As they prepared to tape, the opening notes of the hit song started to play, and the cast looked around, appearing confused, only to see the crew start dancing to the tune. The actors, led by Kaley Cuoco (Penny), join in on the fun.

But "Call Me Maybe" wasn't the only hit the cast and crew danced to. Simon Helberg (Howard) and Kunal Nayyar (Raj)  had their own moment in the spotlight with Kanye West's "Gold Digger," it was guys vs. gals to Jay-Z's "Big Pimpin'," some break dancing moves by Galecki to LMFAO's "Party Rock Anthem," and even some groovin' to Flo Rida. 

What about Parsons, you ask? The man behind ubernerd Sheldon stayed in character the entire time, standing in front of his favorite spot on the couch, staring at the shenanigans, only to deliver one line as the cast got back into their places and the director called "Action!" Check it out:

According to The Hollywood Reporter, the bit was choreographed by Cuoco's sister, Bri.
