As well as accidents in his trousers, Cena also had a bad habit of spitting when he talked. The most infamous incident with his promo spit was when he was feuding with The Rock, and a great big wad of spit came shooting down his chin and on to the mic. Visible on screen, it was a disgusting sight. To make the wackyness even worse, the spit just stayed dangling there for the rest of the scene, even managing to migrate up over his lips. He seemed totally oblivious and just gone on with it!
