A woman came up behind her husband while he was enjoying his morning tea and whacked him on the back of the head. "I found a piece of paper in your back pocket with the name 'MaryLou' written on it," she said, furious. "You had better have a damn good explanation!"
"Honey, please calm down!" the man replied. "Remember last week when I was at the dog track? That was the name of the dog I bet on."
The next morning, his wife snuck up on him and whacked him again.
"What was that for?" he complained.
"Your dog called last night!"
