Check Out The Big Bang Theory Flash Mob

This is just awesome!  I love The Big Bang Theory.  This was originally posted on The Big Bang Theory's Facebook page in November 2012, but this is the first time I've seen it.  Where have I been??!!

During the filming of an episode, the studio audience, show creators Chuck Lorre and Bill Prady and executive producer Steve Molaro were surprised with a dance routine by the cast and crew.

Kaley Cuoco (Penny), Kunal Nayyar (Raj), Melissa Rauch (Bernadette), Simon Helberg (Howard) and even Mayim Bialik (Amy) joined in the mob.  Johnny Galecki (Leonard) eventually joins in.  Jim Parsons (Sheldon) either missed practice, isn't in on the joke or just stayed in character.

They dance to songs from Carly Rae Jepsen, Kanye West, Beyounce, Jay-Z, Ludacris, LMFAO and Flo Rida.

Following the dance, Parsons says in classic Sheldon fashion:  "Bazinga!"
