A man walks into a bar on the top floor of a skyscraper. He sits down and orders a beer. After taking a drink he sees the guy next to him go over to the window and jump out!
"Holy cow! Did you see that!? That guy just jumped out the window!"
The bartender does nothing.
So the man takes another sip. A minute later the same guy walks in, orders another drink, chugs it, and jumps out the window again.
"Jesus! He just jumped again!"
The bartender ignores the man.
So the man sits puzzled. The guy comes back into the bar, and orders another drink.
"How did you survive that jump?".."I ordered a floatie drink, if you drink it in a certain amount of time, you can float."
So the guy quickly orders a 'floatie' drink. He takes it from the bartender, and chugs it. He then jumps out the window and...SPLAT! Right on the sidewalk!
The Bartender then says, "You know, Superman...you can be a real jerk when you're drunk."
