I think that this is a UL, spurred by an old old joke. The joke goes as follows: A man’s sitting at a bar at the top of the World Trade Center (is there really a bar there? don’t ask me) and starts talking to the fellow next to him. He says “you know, the winds up here are so strong that if you jump off the building, they’ll blow you RIGHT BACK.” The guy figures he’s full of it, that he’s being taken for a rube, for a gullible tourist. The first man insists, “No, I’m being serious … if you open the window and jump, the wind will blow you right back!!” Still dubious, the guy figures he’ll call him on it and says “okay, you go first!” So the man at the bar smiles, stands up … goes to the window and jumps out. Sure enough, he comes right back in!

The tourist is completely amazed, and says “wow, I’ve got to try that!!” So he goes to the window, jumps … and falls to his death. The first man sits back down and winks at the bartender, who tells him “Superman, you sure are a mean drunk!”

Okay, not that funny, but the point is, if it’s the basis for a lame joke such as this, it’s not really all that likely to be a true story, but rather an urban legend.
