Great one

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 instructions: "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 t e s t i c les 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.
