A man comes home from work and a gorilla is in his backyard, up in a tree. He calls the gorilla guy, Carl, who shows up with a big dog and a gun. Carl tells the man, "I'm gonna climb up that tree and you hold that gun. When I knock the gorilla out of the tree, the dog is going to chomp down on his yoo-hoo, and hold him until I can climb down and tie him up, so I can take him to the zoo." The owner says, "Okay, but what is the gun for?" And Carl says, "That's in case the gorilla knocks ME out of the tree--then you shoot the dog!"
