Our friend walks into the bar on the top of the Sears Tower. This guy sits down at the bar, has a couple of drinks, turns to the fellow sitting next to him at the bar and says “I bet you I can jump out that window, almost touch the ground, and drift right back up.”
The other guy turns to him and says “No way, I don’t believe you, show me.”
So Our Friend jumps out the window, almost touches the ground, and comes back up.
The other says “Wow, that’s amazing. How did you do that?”
The first guy says “It’s wind currents. A quirk of the design of the Sears Tower is that if you jump out the window the wind will blow you back up here.” They both have a few more drinks, and contemplate this amazing phenomenon.
Our Friend turns to the other guy and says, “I’ll prove it! I bet you I can still jump out that window, almost touch the ground and come back up.”
The second guy says “I think you’re nuts, but go ahead I’ll take the bet.”
So, the first guy jumps out the window, almost touches the ground, and floats right back over the railing
The second guy at this point thinks this is pretty cool, and says “That’s incredible, it looks so easy, I think I’ll try it.”
So the second guy jumps out the window, and crashes SPLAT!!! all over the pavement below. We’re talking, well, ugh…
The bartender shakes his head and says “Superman, y’know you’re a really nasty liar when you’re drunk.”
