A man, visiting the zoo, was standing before the gorilla cage when a gust of wind blew some dust in his eye. He pulled his eyelid down to dislodge the particle and the gorilla went crazy, bent open the bars of his cage, and beat the guy senseless. When he came to, the zookeeper asked him what happened. He explained and the zookeeper said, “I’m not surprised. You see, in gorilla language, pulling down your eyelid means “F*¢k you.” The man vowed revenge. The next day, he purchased two large knives, two party hats, two party horns, and a large sausage. He hurried to the zoo, hid the sausage in his pants, and then went to the gorilla’s cage. He tossed one party hat, one horn, and one knife into the cage. Knowing that apes are natural mimics, he put on his party hat. The gorilla saw him, looked at his hat, and put it on. Then he picked up his horn and blew it. The gorilla picked up his horn and did the same. Then the man picked up his knife, whipped the sausage from his pants, and sliced it neatly in two. The gorilla looked down at his knife, looked at his crotch, looked at the man, and pulled down his eyelid!
