VIDEO: Watch The Cast and Crew of “The Big Bang Theory” Surprise Their Audience With A Flash Mob

And this is why “The Big Bang Theory” is gold.

On October 23, the cast and crew of the hit CBS show surprised its live audience with a flash mob in studio!

Leonard, Sheldon, and the entire gang started off the good time (acting completely surprised at first) with Carly Rae Jepsen’s “Call Me Maybe.”, but soon, transitioned to a number of hits, including Kanye West’s “Gold Digger” (for Howard and Raj), Jay-Z’s “Big Pimpin'” (guys vs girls), and LMFAO’s “Party Rock Anthem” (get ready for some break dancing!) 

Take a look at the video below, and make sure you stay until the end for Jim Parson’s single line, as he stays in completely character as Sheldon!
