The Move: The Undertaker twists his challengers arm before ascending the turnbuckle. Then, still holding his opponents arm, he walks along the top rope, before jumping down and landing a blow to the back of his adversary's head/back. How The Opponent Helps:By providing the balance for the Undertaker to successfully complete his move. Without him, the Undertaker could not walk the rope: it's probably not impossible, but it would likely require a far more nimble competitot like Kofi Kingston, and not a giant of a man like the Undertaker. Why It's Unbelievable: Regardless of Undertaker being wrestling royalty, one of his most famous moves requires a considerable amount of helps from his opponents. In reality, whoever he was facing would simply push Taker off and watch him tumble hilariously to the floor. http://www.youtube.com/watch?v=_E5hjVFEJ2s Which other moves require too much of a suspension of disbelief to keep you locked into the moment?
