There's a bar on top of a really, really high building and it's very windy outside, so it is swaying back and forth.

A guy walks into the bar and has some drinks and is there for a few hours.

Another guy comes and sits next to him.

The first guy who has been there for a while looks at the man and says to him, "You know that there is a nice breeze outside and if you jump out it will blow you right back in."

The second guy doesn't agree and tells him to prove it. So, the first guy jumps out the window and comes soaring right back in.

The second guy asks him to do it one more time. So, the first guy jumps out and the nice breeze takes him right back into the bar.

At this time the second guy is starting to believe him and decides he needs to try this. He then jumps out and falls down to his death.

The bartender turns to the first guy and says, "Superman, your an asshole when your drunk!!"
