The second guy says, "What, are you nuts? There's no way that could happen. "No, its true," the first man says. "Let me prove it to you." He gets up from the bar, jumps over the balcony, and plummets toward the street below. As he nears the 10th floor, the high winds whip him around the building and back into the 10th floor window and he takes the elevator back up to the bar.
He meets the second man, who looks quite astonished. "You know, I saw that with my own eyes, but that must have been a one time fluke." "No, I'll prove it again," says the first man as he jumps again. Just as he is hurtling toward the street, the 10th floor wind gently carries him around the building and into the window. Once upstairs he urges his fellow drinker to try it.
"Well, why not." the second guy says, "It works. I'll try it." 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 and says, "You know Superman, you're a real dick when you're drunk".
