Two men are drinking in a bar at the top of the Empire State Building. One turns to the other and says, "You know, last week I discovered that if you jump from the top of this building by the time you fall to the 10th floor, the winds around the building are so intense that they carry you around the building and back into the window."

The bartender just shakes his head in disapproval while wiping the bar.

The 2nd Man says: "What are you a nut? There is no way that could 
happen."

1st Man: "No it's true let me prove it to you." So he gets up from the bar, jumps over the balcony, and careens to the street below. When he passes the 10th floor, the high wind whips him around the building and back into the 10th floor window and he takes the elevator back up to the bar.

The 2nd Man tells him: "You know I saw that with my own eyes, but that must have been a one time fluke."

1st Man: "No, I'll prove it again" and again he jumps and hurtles toward the street where the 10th floor wind gently carries him around the building and into the window. Once upstairs he urges his fellow drinker to try it.

2nd Man: "Well, what the hell, it works, I'll try it." So he jumps over the 
balcony, plunges downward, passes the 11th, 10th, 9th, 8th floors and hits the sidewalk with a 'splat.'

Back upstairs the Bartender turns to the other drinker: "You know, Superman, you're really a jerk when you're drunk."
