Babysitter

A boy was taking care of his baby sister while his parents went to town shopping. He decided to go fishing and he had to take her along.

"I'll never do that again!" he told his mother that evening. "I didn't catch a thing!"

"Oh, next time I'm sure she'll be quiet and not scare the fish away," his mother said.

The boy said, "It wasn't that. She ate all the bait."
