Once upon a time, there was a man who went to the zoo. He stopped by the gorilla cage. There is a big sign there that says "Do NOT touch the gorilla!" Somehow the man accidentally touched the gorilla.

A few minutes later he goes into his car and drives home. While he drives on the freeway he sees in his rear view mirror the gorilla driving a few feet away from home.

Being scared the man goes to an airport flying from New York to Los Angeles. He looks back on the airplane and there is the same gorilla there.

After he gets off at Los Angeles the guy tries to swim to China. After quite some time he looks back and sure enough the gorilla is also swimming to China.

When he finally reaches China, the man who is out of breath by now. Sitting down he rests for awhile. By now the gorilla is only a few feet away from him.

The guy says to him, "What do you want from me? Why do you keep chasing me?"

The gorilla taps him on the shoulder and says to the man, "Tag! You're it!"
