The telephone rings in the principal's office at a school.

"Hello, this is Dunn Elementary," answers the principal.

"Hi. Jimmy won't be able to come to school all next week," replies the voice.

"Well, what seems to be the problem with him?"

We are all going on a family vacation," says the voice,

"I hope it is all right."

"I guess that would be fine," says the principal. "May I ask who is calling?"

"Sure. This is my father!"
