On the top of a tall building in a large city, there was a bar. In this bar, a man was drinking heavily. He would ask the bartender for a tequila shot, then walk out to the balcony and jump off. Minutes later, he would appear in the elevator and repeat the whole process.
This one guy watched this happen a number of times until curiosity got the better of him. Finally, he went up to the man and asked, "Hey, you keep drinking, then jumping off the balcony. And yet, minutes later, you're back again. How do you do it?"
"Well, the shot of tequila provides buoyancy such that when I get near the ground, I slow down and land gently. It's lots of fun. You should try it."
The guy, who was also quite drunk, thought to himself, "Hey, why not?" So he goes to the bar, drinks a shot of tequila, then walks out to the balcony, jumps off, and whooooooooooooo, splat.
The bartender looks over at the first guy and says, "Superman, you're so bad when you're drunk."
