Remember that brilliant surprise flash mob sequence from 2012? The one in which the cast of The Big Bang Theory surprised their live audience with a choreographed dance to the likes of Call Me Maybe, Party Rock Anthem and Low? Well that was organised by none other than Kaley Cuoco herself. Having recruited her sister Briana (who has also appeared on the show) in order for her to help with the choreography, the actress thought it would be a nice surprise for those who had gone to the trouble of travelling to the live show and the cast pulled it off brilliantly. A 2014 version occurred under similar circumstances, with the cast dancing to Uptown Funk. The 2012 effort is pictured above and the 2014 version can be watched in all its glory in the video below. https://www.youtube.com/watch?v=ODOmKIrZ4WU
