A dog is so smart that his master decides to send him to college.
Home for vacation, his master asks him how college is going.
"Well," says the dog, "I'm not doing too great in science and math, but I have made a lot of progress in foreign languages."
"Really?" says the master. "Say something in a foreign language."
The dog says, "Meow!"
The city boy goes to countryside to visit his uncle. After the sun goes down, the boy hears strange, another-world howling. He gets frightened and runs to his uncle. "Uncle, uncle, there are werewolves!"
"That's rubbish, boy, ain't no such thing".
"'Then, there must be man-eating wolves".
"No, we haven't got those buddies, either."
"What is this sound, then?" the boy asks.
"They are coyotes".
"Coyotes? What are those?"
"They look a lot like dogs. In fact, ya can consider them a kind of dog."
The boy wants to find out more: "Why are they making that frightening noise?"
"See, nephew, we ain't got many trees around here. We got cactuses!"
