Two guys are drinking in a fourth floor bar. The first guy finishes his drink, says, "I'm done," and jumps out an open window and then blows right back in. "Gosh, the wind is strong tonight," he says.
The second guy takes all that in, finishes his drink, goes to the window, and jumps out. He falls to his death.
The bartender turns to the first guy and says, "Superman, you're a real jerk when your're drunk."
