A man walked into his backyard one morning and found there was 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 instinctivly crosses his hands in front to protect himself, you slap the handcuffs on”

“Ok, got it.” the homeowner replied. “But whats that shotgun for?”

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