When John Cena hit CM Punk with a rather dodgy looking Hurricanrana in 2013, it cemented just how physically impossible the move is. Like an 80-year old Rey Mysterio in slow motion, Cena delivered one of the worst variations of the move in wrestling history, and the announcers promptly went nuts, as though the guy had just cured Cancer and banished war from the plains of our earth. In fairness to Cena, high-flying really isn't his thing, which makes it all the more confusing why he'd choose to bust out a move such as this during a high-profile encounter. Our only guess is that he did it once on a house show, and somebody backstage was impressed. Quicker wrestlers can make the Hurricanrana look flashy, but here it becomes obvious that Punk has to do a forward flip. Gravity would dictate that if Cena were to jump at Punk like that, the latter would simply collapse backwards, both due to the weight of the man leaping onto his chest, and also the fact he's jumping towards him.
