CLIFF, bit sick!

A couple of strangers were drinking at a cliffside bar overlooking
the ocean. Both of them look a little drunk, when one says to
the other: "Hey, look at the wind whipping up the side of that
cliff. It moves pretty fast. I'll bet I could jump off of the
ledge, catch the wind in my coat, and get lifted right back up to
the bar!"

"No way", says the other guy, "you'd fall to your death."

"Well, I'm going to try it!", says the first, and at that he walks
over, stands on the ledge, and leaps off in a swan dive. Sure
enough, he comes sailing back up in no time, and lands on his feet
right in front of the bar.

"I can't believe it!" says the second guy, "that's impossible" .
So the first drunk does it again: he jumps off the cliff, catches
the wind in his coat, and comes sailing back to the bar.

"Go ahead", he says, "try it, it's great!"

"Well, OK, I'm just drunk enough to give it a go", says the second
fellow. So he climbs the ledge and leaps off the cliff, only to
fall screaming to his death on the rocks below.

The first guy walks back to the bar and sits down to his drink.
The bartender steps over, looks him in the eye, and says to him:
"You know, you can be a real jerk sometimes when you've been
drinking, Superman".
