Don't Talk With Your Mouth Full

These three men went out for a drive in the country and their car broke down, so they went to the nearest farmhouse to ask for shelter for the night.

"Sure lads," said the farmer. "You can spend the night here, but you've got to sleep with one of my daughters, 'cause they don't get much company out here." The three men were of course more than happy to oblige.

The following morning, the men went on their way and the farmer called his daughters together.

"Linda, why were you laughing last night?
"Because it tickled Daddy."

"Susie, why were you crying?"
"Because it hurt Daddy."

"Lizzie, why was YOUR room so QUIET?"
"That's because you always told me not to talk with my mouth full."
