The bartender just shook his head in disapproval while wiping the bar.
The second guy said, "What are you, crazy? There is no way that could happen."
The first guy was adamant, "No it’s true let me prove it to you." So he got up from the bar, jumped over the balcony, and started falling to the street below. When he passed the tenth floor, the high wind whipped him around the building and back into the tenth-floor window and he took the elevator back up to the bar.
The second guy said, "You know I saw that with my own eyes, but that must have been a one-time fluke."
The first guy said, "No, I’ll prove it again" and again he jumped and hurtled toward the street where the tenth-floor wind gently carried him around the building and into the window.
Once upstairs he urged his fellow drinker to try it.
The second guy thought for a moment and said, "Well what the hell, it works, I’ll try it." He jumped over the balcony, plunged downward, passed the eleventh, tenth, ninth, eighth floors... and hit the sidewalk with a ‘splat.’
Back upstairs the bartender turned to the first guy and said, "You know, Superman, you’re a real jerk when you’re drunk."
