A bus carrying only ugly people crashes into an oncoming truck and everyone inside dies. They then get to meet their maker and because of the grief they have experienced, he decides to grant them one wish before they enter Paradise.
They're all lined up and God asks the first one what the wish is. "I want to be gorgeous," and so God snaps His fingers and it is done. The second one in line hears this and says "I want to be gorgeous too." Another snap of His fingers and the wish is granted.
This goes on for a while but when God is halfway down the line, the last guy in line starts laughing. When there are only ten people left, this guy is rolling on the floor, laughing his tail off.
Finally, God reaches this guy and asks him what his wish will be. The guy calms down and says: "Make 'em all ugly again."
