Three kids are talking about their fathers and comparing them.
First kid says: "My dad is the fastest. He’s a drag racer and can do a quarter mile in 9.6 seconds."
Second kid says: "That’s nothing! My dad is a fighter pilot and regularly breaks the speed of sound."
Third kid says: "My dad is faster than both your dads! He’s a congressman. He finishes work at 4 o’clock but is always home by lunchtime."
