There are these three guys on top of the CN Tower in Toronto. One guy told the other that he could jump of of the top and land right back where he's standing. The other guy didn't believe him, so the first guy jumps off, and ends up right back where he was standing. Now the second guy just had to try it. He jumps off and plummets to the ground. The third guy says to the first, "Geez, Superman, you can be a real jerk sometimes!"
