A man wakes up one morning to find a gorilla on his roof. So helooks in the yellow pages and sure enough, there's an ad forGorilla Removers. He calls the number, and the gorilla removersays he'll be over in 30 minutes.

The gorilla remover arrives, and gets out of his van. He's got aladder, a baseball bat, a shotgun and a mean old pit bull.

What are you going to do? the homeowner asks.

I'm going to put this ladder up against the roof, then I'm goingto go up there and knock the gorilla off the roof with thisbaseball bat. When the gorilla falls off, the pit bull is trainedto grab his testicles and not let go. The gorilla will then besubdued enough for me to put him in the cage in the back of thevan.

So the guy puts the ladder up, gets the bat and the shotgun andwalks towards the ladder. As he gets to the base of the ladder,he hands the shotgun to the homeowner.

What's the shotgun for? asks the homeowner.

If the gorilla knocks me off the roof, shoot the damn dog!
