A dangerous job

This guy wakes up one morning to find a gorilla in his tree. He looks in the phone book for a gorilla removal service until he finds one. "Is it a boy or girl Gorilla?" the service guy asks. "Boy," is the man's response. "Oh yeah, I can do it. I'll be right there," says the service guy. An hour later the service guy shows up with a stick, a Chihuahua, a shotgun, and a pair of handcuffs. He then gives the man some nstructions: "Now, I'm going to climb this tree and poke the gorilla with the stick until he falls. When he does, the trained Chihuahua will bite the gorilla's testicles off. The gorilla will then cross his hands to protect himself and allow you to put the handcuffs on him." The man asks, "What do I do with the shotgun?" The service guy replies, "If I fall out of the tree before the gorilla, shoot the Chihuahua."
