How fast?

[lacanteen]

These three boys are in the schoolyard bragging of how great their fathers are. First boy 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". Second one says: "Ha! You think that's fast! My father is a hunter. He can shoot his gun and be there before the bullet!" The third one listens to the other two and shakes his head. He then says "You two know nothing about fast. My father works for the state. He finishes work at 4:30 and he is home by 3:45!"
