The other man is incredulous, and asks the man to jump and prove it. To this the man says sure, and without hesitation heads over to the balcony and jumps off. Sure enough, a few feet down, he suddenly changes direction and swoops back up on to the balcony. The man is impressed. "I gotta try this!" he says and leaps off the balcony. He goes straight down, and splats on the pavement below. The bartender turns to the first man and says "Superman, you sure are a mean drunk."
