This is one of my favorite jokes:

Two guys are in a bar on 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 hears this, and just shakes his head in disapproval while wiping down the bar.

The second man is likewise incredulous. "Are you nuts?" he says. "There's no way in hell that could happen!"

The first man says, "It's true! Watch!" He gets up from the bar, jumps over the balcony, hurtles toward the ground. When he passes the 10th floor, he is whipped around the building and into a window. He takes the elevator back up to the bar.

The second man is aghast. "I don't believe it. It's gotta be a fluke."

And the first man repeats the trick.

Once he returns to the bar, he urges his fellow drinker to try it. The second man finally relents. He jumps over the balcony, plunges past the tenth floor and dies with a splat when he hits the ground.

The first man is peering over the edge. The bartender joins him on the ledge.

"You know," the bartender says, "you're a real asshole when you're drunk, Superman."
