What with the dancing in the NFL?

Yeah, it's annoying. But my biggest peeve is when a defensive player is completely owned by a wide receiver, only to have the quarterback make a bad throw, making the receiver stop and giving the defensive player time to get back into the play. At which point he barely deflects the ball and starts jumping up and down like he just made the single greatest play in history. Complete with the grossly exaggerated incomplete signal with his arms.
