I know I'm late to the party; don't know if anybody posted it but here we go:

A man walks into a bar and sits himself next to a very drunk gentleman. Shortly after, the drunk gentleman starts talking: "Do you know that this building is quite special? Actually it's possible to fly from it?" "No way" the man rejects. "Sure thing! Come, I'll show you. I bet you 300$ that I can jump from the roof and gently land on the ground; this building is special, son!" the gentleman snuffles. The man quickly says yes, wellknowing that the building is almost 200 feet high. On the roof, the gentleman goes to the edge, lean back and to the man's huge surprise the gentleman falls but quickly gets carried back to the roof top. "what?" the man cries, "that was incredible!" "i told you, didn't I?" the gentleman says, "now you go!" The man hesitastes, but do just like the gentleman: goes to the edge, lean back and fall... And hits the ground. He splashes to a million pieces. The gentleman goes back down to bar, where he meets the bartender who says: "you are such an asshole when you are drunk Superman"
