10 Most Shocking Wrestling Heel Turns

There are few sights in wrestling more shocking than that of a barely-conscious JR being made to kiss Vince McMahon's naked ass.

And if it were Kurt Angle alone, or just about any other wrestler on the roster, forcing Raw's beloved commentator to pucker up, it would have been slightly easier to watch - but there was something truly striking about the fact that it was Undertaker.

WWE's resident vigilante had spent the previous decade largely locking horns with foes who outreached him, only setting his sights on the helpless when they truly deserved it (sacrificial lamb Stephanie McMahon, for example).

For him to attack a commentator, after appearing to come to his aid, was a heel turn against which few can be compared in terms of shock value, thanks in no small part to the brilliant way in which Big Evil - one of wrestling's most underrated talkers - set it up.

After telling JR that everyone else in the locker room, at one point or another, had to kiss the chairman's ass, 'Taker asked whether he was planning to follow suit. "No" - and, by implication, "I'm better than you" - was the wrong answer.
