Mother-in-law

Two friends are talking in a bar.

“My Mother-In-Law died yesterday!” said the first.

“Sorry to hear that,” replied his friend. “How did she die?”

“Well. She sat down in the chair, put her feet up, laid back closed her eyes, and that was it.”

“Hmmm. Suppose it's a nice way to go.”

“Yeah,” said the first guy. “But the dentist wet his pants!”
