Removing a Gorilla

A man walked into his back yard one morning and found a gorilla in a tree. He called a gorilla-removal service, and soon a serviceman arrived with a stick, a Chihuahua, a pair of handcuffs, and a shotgun.

"Now listen carefully," he told the homeowner. "I'm going to climb the tree and poke the gorilla with this stick until he falls to the ground. The trained Chihuahua will then go right for his, uh, sensitive area, and when the gorilla instinctively crosses his hands in front to protect himself, you slap on the handcuffs."

"Got it," the homeowner replied. "But what's the shotgun for?"

"If I fall out of the tree before the gorilla," the man said, "shoot the Chihuahua."
