Haha. Easiest bet you ever won. It is definitely the same guy. I don't even understand why he would think otherwise. If Miz were to leave, Die or whatever they wouldn't get a look alike for him.
I remember when there was the same rumor when I was in high school about Ultimate Warrior. The rumor that was spreading then was he died of a heart attack and there was someone else playing the Warrior role. What started that was because he came back at WM8 with darker and shorter hair and he wasn't quite as big. There were people out there that even though Kerry Von Erich was pulling double duty and was Ultimate Warrior as well as himself. At least Warrior wore makeup though so that helped keep the rumor alive.
