Two guys are drinking in a fancy bar at the top of a skyscraper.

One of the guys downs a shot of whiskey and jumps out the window.

The other guy is shocked to see the first one arrive back in the bar a few moments later.

"How did you do that?" he asks.

"It's simple," the first guy says. "You just take a shot, then jump out the window and you float to the ground."

The second guy decides to give it a try. He throws back a shot, jumps out the window, and plummets to his death.

The bartender brings another shot to the first guy and says, "Superman, you sure are an asshole when you drink."
