Despite Carly Rae Jepsen's 'Call Me Maybe' being the most played (and therefore the most reviled) song of the year, you're dead inside if you're not amused by this flash mob organized by 'The Big Bang Theory' cast and crew to surprise their show runners.

Chuck Lorre, Bill Prady and Steve Molaro were trying to film a scene of their hit CBS sitcom during an Oct. 23 live taping, but when they called "action," the viral hit song played instead.

The principal cast looked around in confusion as a few crew members started to dance before most of the actors joined in themselves and the audience lost their collective stuffing.

Kaley Cuoco (Penny), Kunal Nayyar (Raj), Simon Helberg (Howard), Mayim Bialik (Blossom Amy) and Melissa Rauch (Bernadette) all joined in on the fun while Johnny Galecki (Leonard) and Jim Parsons (Sheldon) watched from the set. Because nerds can't dance, duh.

After the mini-flash mob -- the brainchild of Cuoco and choreographed by her sister Bri -- they returned to filming as if flash mobs happen on their set on the regular.

The end of the stunt is signaled by Emmy winner Parsons, who spouts out his trademark “Bazinga!”

Which roughly translates to, “Take that Chuck Lorre, we just pwned your ass on your own set.”
