Sure Bet

This 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. Smack!
�Ouch! What was that for?�
�What was that piece of paper in your pants pocket with the name Mary Lou written on it?�
�Oh honey, remember two weeks ago when I went to the horse races?
Mary Lou was the name of one of the horses I bet on.�
�Oh,� she says and goes about doing her housework, apparently happy with his answer.
Three days later he is once again sitting in his chair reading, when - WHACK! - His wife again hits him over the head with a frying pan again.
�What the heck was that for this time?�
�Your horse phoned.�
