The answer (in case you didn’t bother clicking on any of the links): They’re all featured in enormously popular “Call Me Maybe”-themed viral videos.
And now it looks like we can add the cast of The Big Bang Theory to that list. A video of the cast and crew dancing to the Carly Rae Jepsen hit was uploaded to YouTube yesterday, and already it has amassed two million views.
The lesson to take away from all this? If you want to make a viral video, be someone famous, then film yourself singing or dancing to “Call Me Maybe.”
