They're all lined up, and God asks the first one what their wish is.

 

"I want to be gorgeous." 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 with each one asking to be gorgeous, but when God is half way down the line, the last guy in the line starts laughing. When there are only ten people left, this guy is rolling on the floor, laughing his head off.

 

Finally, God reaches this last guy and asks him what his wish will be.  The guy eventually calms down and says: "Make 'em all ugly again."

 

So, the next time you are last in line...smile!
