Gorilla Problem

A guy wakes up one morning to find a gorilla in his tree. He looks in the phone book and sure enough finds an ad for “Gorilla Pest Control.” When he asks if they can remove the gorilla, the service guy asks, “Is it male or female?”
“Male,” he replies.
“Oh yeah, we can do that. I’ll be right there,” he states.
An hour later, the service guy shows up with a stick, a Rottweiler, a shotgun, and a large pair of handcuffs. He then gives the man some instructions. “I’m going to climb this tree and poke the gorilla with the stick until he falls out of the tree. When he does, the trained Rotty will move in and savage the gorilla’s private parts. The gorilla will then cross his hands across his crotch to protect himself, and that’s when you move in with the handcuffs!”
The man goes pale and asks, “Um, okay, but what do I do with the shotgun?”
The service guy replies, “Hopefully nothing, but if I happen to fall out of the tree before the gorilla, you’ve got to shoot that Rottweiler!”
