These two guys are talking in a bar located high atop a skyscraper. They’re the only guys in there, except for the bartender.
The first guy is in a business suit and glasses, and it’s clear he’s had a lot to drink. He’s telling the second guy that the winds are so strong up here, that if someone steps off the balcony, they wouldn’t hit the ground. They’d be pushed back up to where they could climb back in.
The second guy obviously doesn’t buy it. “That’s ridiculous! I’ve never heard of such a thing,” the guy says. “Prove it!”
The first guy finishes his drink in one last gulp, wipes his mouth, and appears to screw up his courage. “OK, fine” he says. He walks over to the balcony, and steps up on the ledge. He’s staggering a little, and the wind is at least strong enough to blow back his tie and make him even more wobbly.
He turns around to face the bar, holds out his arms, and falls backward. The second guy didn’t think that he’d do it, and yells out and runs over to the balcony to look.
Just as he gets there, the first guy floats up on his back and, buoyed up by the wind, yells, “Quick, pull me in!” The second guy, completely astonished, grabs onto his arm and pulls him back onto the balcony.
“That’s the most incredible thing I’ve ever seen!”
“Oh, man, it’s great fun! You should try it!”
The second guy thinks a minute. Maybe he has had enough to drink, after all. He steps up on the balcony ledge, takes a look down, and then turns around and falls backward, just as the first guy had done.
However, the second guy falls straight down and lands in the street far far below.
The first guy walks over to the bar, grinning like a fool.
The bartender looks up, disgusted. “You’re a real asshole when you’re drunk, Superman.”
