Caught Swearing

The little boy was caught swearing by his teacher.

"Billy," she said, "you shouldn't use that kind of language. Where did you hear it?"

"My daddy said it," he responded.

"Well, that doesn't matter," she explained, "I don't want to hear that language in here again."

Then she said, under her breath, "At least he doesn't know what it means."

"I do, too," Billy corrected. "It means the car won't start!"
