This guy went to the zoo one day. While he was standing
in front of the gorilla's enclosure, the wind gusted and he got
some grit in his eye. As he pulled his eyelid down to
dislodge the particle, the gorilla went crazy, bent open the
bars, and beat the guy senseless. When the guy came to,
the zookeeper was anxiously bending over him, and as soon
as he was able to talk, he explained what had happened.
The zookeeper nodded and explained that in gorilla
language, pulling down your eyelid means "fuck you".
The explanation didn't make the gorilla's victim feel any
better and he vowed revenge. The next day he purchased
two large knives, two party hats, two party horns, and a large
sausage. Putting the sausage in his pants, he hurried to the
zoo and over to the gorilla's cage, into which he tossed a hat,
a knife, and a party horn.
Knowing that the big apes were natural mimics, he put on
a party hat. The gorilla looked at him, and looked at the hat,
and put it on. Next he picked up his horn and blew on it.
The gorilla picked up his horn and did the same. Then the
man picked up his knife, whipped the sausage out of his
pants, and sliced it neatly in two.
The gorilla looked at the knife in his cage, looked at his
own crotch, and pulled down his eyelid.
