A fool is walking down the street, dragging a brick on a leash behind him.

A cop sees him and says to himself: “I’ll make fun of him.”

He walks up to him and says: “Gee, you’ve got a nice dog!”

The fool replies, “Are you crazy? That’s a brick!”

The angry cop walks away.

The fool turns to the brick and says, “We got him, didn’t we, Rex?”
