My Dad Is Faster

Three boys are in the school yard bragging about how fast their fathers
are.

The first one says, "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 replies, "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
government. He works until 4:30 and he is home by 3:45!"
