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

The first one 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". 

The 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 is a civil servant. 

He gets off work at 5 and is home before 4"!!
