The Truck

  Just before a drafted farm boy made his first parachute jump,
his sergeant reminded him, "Count to ten and pull the first rip cord.
If it snarls, pull the second rip cord for the auxiliary chute.  After
you land, our truck will pick you up."

  The paratrooper took a deep breath and jumped.  He counted to
ten, and pulled the first cord.  Nothing happened.  He pulled the second
cord.  Again, nothing happened. As he careened crazily earthward, he
said to himself:  "Now I'll bet that truck won't be there either!"
