"Marylou" joke

A man was sitting quietly reading his paper one
morning, peacefully enjoying himself, when his wife
sneaks up behind him and whacks him on the back of his
head with a huge frying pan.
MAN: "What was that for?"
WIFE: "What was that piece of paper in your pants
pocket with
the name Marylou written on it?"
MAN: "Oh honey, remember two weeks ago when I went to
the horse races? Marylou was the name of one of the
horses I bet on."
The wife looked all satisfied, apologizes, and goes
off to do work
around the house. Three days later he is once again
sitting in his
chair reading and she repeats the frying pan
swatting.
MAN: "What was that for this time?"
WIFE: "Your horse phoned."
