Following an especially angry argument, Ma and Pa went to bed not speaking to each other.
Needing to arise early the following morning, Pa left a note on his wife's bedside table:
"Woman," it began, "Wake me at six."
Pa awoke at ten the following morning. Much aggravated, he rolled stiffly out of bed to see a note on his bedside table:
"It's six, Man, Get out of bed!"
