The world's greatest joke...

One night a man is walking his dog named Fido down the street when he spots a man on his hands and knees under a streetlight. The dog walker then asks the man if he has lost anything? Man says "yeah i lost my contact lens." So the dog walker ties Fido to a phone pole and gets down on his hands and knees to help. They search up and down, back and forth beneath that light. Fifteen minutes later the dog walker (yes fido is still tied up so we are still calling him the dog walker) says "buddy i can't find it anywhere. Are you sure it popped out here?" The man says "No i lost it over in the park." "The park?!" the dog walker says, "Then why the hell are you looking for it in the street?" The man then points to the streetlight and says "Better light here..."

Why is this the worlds greatest joke? Because given the choice between groping in the dark and searching hopelessly in the light, ninety-nine out of a hundred would pick the light everytime...
