Apropos of Nothing

"I love driving a cab. But you've got to be careful. Few nights ago I had a gun in my cab. Guy got in, and I said, either you give me that gun or you're gettin' out. He gave me the gun. When we got back from the crack house, he was so happy to have his drugs, he got out of the cab and forgot about the gun. I sold that gun to a cop."
