Big Bang Theory Flash Mob Video - MUST SEE!

As purveyors of the finest Big Bang Theory t-shirts around, we don't quite know how we missed seeing this little gem of a video that surfaced on YouTube a couple of months back.

In October last year Kaley Cuoco, who plays Penny, arranged a flash-mob which included the entire cast and crew of the show. During filming, Carly Rae Jepson's "Call Me Maybe" started playing in the studio, to which the flash-mob starts. Watch the video below to see an amazing performance including Gold Digger, Run the World, Big Pimpin' and Party Rock.

What we'd have given to be in the live studio audience that day!
