Fast Dads

Those three boys are in the schoolyard bragging of how great their
fathers are.

Danny says, "Well, my father runs the fastest. He can fire an
arrow, and start to run, I tell you, he gets there before the arrow".

"Ha! You think that's fast! My father is a hunter. He can shoot his 
gun and be there before the bullet", declares Billy.

Little Johnny listens to the other two and shakes his head. Then he
exclaims, "You two know nothing about fast. My dad is a civil servant. 
He gets off work 4:30, but he's usually home by 3:15!"
