Woah. Supernatural s4 e6 Yellow Fever was now the funniest episode i've ever watched. It beat the Rabbit's Foot episode. Strangly enough, in the Rabbit's Foot episode, Sam was the one acting funny while in Yellow Fever it was Dean. Dean really own it, screaming like a banshee in one part and lip singing eye of the tiger at the end. =D Funny. This episode makes my day.
