A man walked into his backyard in a residential neighborhood one morning. He saw a 600 pound Gorilla sitting in his tree. He telephoned an emergency Gorilla Removal Service, and shortly a technician arrived with a stick, a pair of hand cuffs, a tiny Chihuahua, and a shotgun.

"Now listen carefully", he told the homeowner. "I am going to climb the tree, and poke the Gorilla with this stick, until he falls to the ground. My trained Chihuahua will go right for the Gorilla's testicles, and when the Gorilla instinctively crosses his hands over his testicles to protect himself, you slap on the hand cuffs without delay."

"OK... got it," the homeowner replied. "But what is the shotgun for?"

Said the technician... "If I should fall out of the tree before the Gorilla... SHOOT the Chihuahua!!!"
