So little Timmy was born with only a head. He did fine, considering his...limitations. As he grew older, his Mom used to sit him on top of the couch in front of the living room window to watch the kids play outside.
One day, Timmy is a little pissed. He can't join the kids in their play. So he prays to God, "God, I wish I had a body." BAM!!! He has a body! Timmy looks down in astonishment! So, he thinks, why not? "God, I wish I had arms." BAM!! He has arms! This is so cool, thinks little Timmy. So, once again, "God, I wish I had legs." You guessed it, little Timmy had legs.
Little Timmy hops down from the couch, yells to his Mom, "Mom, I'm going out to play!" Before she can say a word, little Timmy is out the door. He see's the kid's ball roll out into the street, so he takes off after it...and is hit by a Mack truck, is killed instantly...
Moral of the story? Quit while your a head...
