‘Big Bang Theory’ Cast, Crew Surprise Audience With Flash Mob Dance (Video)

Kaley Cuoco leads the cast of CBS' hit sitcom in an entertaining flash mob dance to Carly Rae Jepsen's "Call Me Maybe"

Contrary to what many might think, sitcom tapings can be long and boring.  The studio audience is forced to laugh as obnoxiously as possible at jokes they've heard five takes in a row and are only rewarded with a measly slice of pizza for dinner.

Kaley Cuoco must have taken notice because during the taping of Thursday's "Big Bang Theory" episode, she organized a special treat for those providing the laugh track.  

Watch the cast and crew of the CBS ratings juggernaut surprise the audience and creator Chuck Lorre with a meticulously choreographed flash mob dance to Carly Rae Jepsen's "Call Me Maybe."

After the routine reaches its end, the actors casually resume their marks and quietly wait for Jim Parsons to deliver Sheldon's catch phrase, "Bazinga!"  

Now that's comedic timing.
