5 Best Moments From The Big Bang Theory

2. "Bazinga, Punk" - Sheldon The Zombie

http://www.youtube.com/watch?v=JJHbnMATqGc In season 5 of the show, Sheldon becomes frustrated after the gang play a harmless Halloween prank on him in "The Good Guy Fluctuation" which scares him witless. Determined to exact revenge, Sheldon carefully plans a series of elaborate pranks on his friends but all of them go awry, that is, until he seemingly tricks Howard with an "electric handshake" which causes the engineer to collapse to the ground. A panic stricken Sheldon is then ordered by Bernadette to inject adrenaline into his friend's heart to save him, but is astonished when he realises he has once more fallen fowl of yet another rouse. He does eventually get his own back though, and it comes at perhaps the worst possible moment as Leonard is sitting in the living room crestfallen having found out his girlfriend Priya recently slept with her ex. As the news sinks in, Sheldon, donned with zombie face paint, springs out from under a sofa cushion causing his friend to leap up in alarm. A serious moment in the episode is thus lightened by Sheldon's brilliance.
