It was a warm, sunny Sunday, so a man and his wife decided to take in the zoo. They spent the day, and at closing time they walked past the gorilla cage, and the man noticed the gorilla looking at his wife.

"That gorilla is getting excited just looking at your tits," he said. "Why don't you take your blouse off and we'll see what he does?"

At first she declined. But finally persuaded by her husband, she took off her blouse and bra. The gorilla went nuts. He started grunting and jumping up and down.

"Hey," the husband said, "let's really blow his mind. Take off all your clothes and we'll see what he does."

Again she said no and again he persuaded her. This time the ape really went bananas! He climbed up and down the bars, did flips, ran around in circles and tossed his food all over the cage.

The husband went over to the cage, opened the door and pushed his wife in.

"Now," said the husband with an evil smile, "tell HIM you have a headache!"
