How Many Eyes
Riddle: How many eyes does it take to outstare a goldfish, if one person is blind, and the other is wearing glasses?
Answer: None, in order to stare, you have to see, but if you were wearing glasses you would just be staring at the glass. So in order to outstare a gold fish, you would have to have no eyelids, which would be impossible for the eye to function properly.
