The mother and father had just given their teenage daughter family-car
privileges. On Saturday night she returned home very late from a
party.
The next morning her father went out to the driveway to get the
newspaper and came back into the house frowning. At 11:30 AM the girl
sleepily walked into the kitchen, and her father asked her,
"Sweetheart, what time did you get in last night?"
"Not too late, Dad." she replied nervously.
Dead-panned, her father said, "Then, my precious one, I'll have to
talk with the paperboy about putting my paper under the front tire of
the car."
