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.Which other moves require too much of a suspension of disbelief to keep you locked into the moment?
