I've heard the following second half of a story:
A policeman got out of the car and saw the boy. He walked up to him and said amiably, "What's your name?"
"Shut up!" the boy replied.
"Where's your manners?" asked the affronted policeman.
"Up that tree," said the boy offhandedly, pointing to a nearby tree.
"You're looking for trouble, aren't you?" said the policeman.
"No, trouble's looking for me!" the boy answered earnestly.
Can you fill in the first half, or somehow explain the strange conversation? The boy is not being intentionally rude, and his answers all make sense when interpreted correctly.
