One day Lopes is walking home when he notices a huge gorilla standing on the roof of his house.
Not knowing what to do about it he looks in the phone book under GORILLA REMOVALS. Then he calls up Willy's Get Lost Gorilla Service and explains the situation.
Ten minutes later Willy arrives with a banana, a bulldog, a butterfly net, a ladder and a loaded gun.
"Okay," says Willy, "it is quite a simple thing. I am gonna throw the banana at the gorilla, and while he is busy eating it, I am gonna climb up the ladder and push him off the roof.
"Then the bulldog is trained to grab him by the nuts, and when the gorilla holds himself in pain, you throw this butterfly net over him."
"Great!" shouts Lopes, with enthusiasm.
"But what about the gun?"
"Well," explains Willy, "if I miss the gorilla and fall off the roof myself, you shoot the dog!"
