A man woke up one morning, looked out the window, and saw a huge gorilla in the tree in his back yard. Feeling very nervous, he grabbed the phone book and looked up 'gorilla exterminators' in the Yellow Pages.
He called the exterminator, who said he would be right out. The exterminator arrived in a van, hopped out, and opened the door. He took out a large net, a shotgun, and a fierce-looking dog.
"OK", he said, "this is how it works, I climb the tree and shake it and the gorilla falls to the ground. The dog runs over and bites him in a vital spot. While he's disabled, you throw the net over him. I'll come down and we'll tie him up".
As the exterminator started up the tree, the man called, "What do I do with the shotgun?" The exterminator said, "Sometimes when I shake the tree, the gorilla shakes it back and I fall out of the tree. If that happens ...... you shoot the dog".
