So this guy goes to a new bar he's heard about; way up on the roof of a skyscraper in a big city. There's only one other guy at the bar, obviously very drunk, but he greets the newcomer heartily and offers to buy him a drink. Soon they're drinking buddies, and soon after that, the new guy is half in the bag, too.
"This place is sumpin'- what a view!" he notes.
"Sure is," the other guy says. "And you know what the best part is?"
"Nope".
"Well, I'll tell ya... on a windy day like this, a guy can jump right off the roof here, and due to various pertiklers of architecture and meeter-urrologisms, before he hits the ground, the wind will whisk him right back up to this very spot, without a scratch!"
The new guy laughs it off, so to prove his point, the other guy hops off his barstool and vaults over the railing.
Horrified, the newcomer watches as the man plummets toward the street below... then is amazed as, sure enough, the guy seems to float back up, making a perfect landing on his feet by the bar!!
"Wow!! That was- watch my drink, barkeep- I'll be right back!"
The new guy hurls himself over the railing, and falls to land with a sickening splat on the street far below.
The first guy chuckles to himself as the bartender brings him a fresh drink. He says:
"Y'know, Superman, you're a real jerk when you're drunk..."
