Ok, here's one

Two guys are sitting in a bar on the 60th story of the sears tower in Chicago. The first guy turns to the other and asks "You know why they call this the windy city?" to which the second guy replies "no, why do they?"
"Well," says the second guy, " it's because there is so much wind in the city, obviously. however, did you know the wind is so strong that if you were to jump out one of the windows of this bar, you'd fall to about the 20th story, be caught by the wind, and shot right back up here?"

"You're full of shit!" the second guy exclaimed.

"Watch" says the first guy as he jumps out the window. Sure enough he falls to about the 20th story and all of a sudden he is shot straight up and back into the bar.

"That's amazing" says the second guy, " I have to try this". He then jumps out the window, falls 60 stories, and dies on impact.

The bartender turns to the first guy and says" Superman, you're a real asshole when you're drunk."
