14. Beating Brock Lesnar
So many people really did shout out "what the f***" with this one. Brock Lesnar was returning to WWE off the back of an ultra-successful run in the UFC. He was one of the biggest box office draws in the world, having set UFC's PPV record of 1.6 million buys at UFC 100. WWE were legitimately getting a mainstream megastar. So what did they do with him? Have him lose to John Cena. It was one of the most surprising victories of Cena's career. WWE had just spent five million on Lesnar, just to have him lose to a long established star? It doesn't make sense.
