A woman came up behind her husband while he was enjoying his morning coffee
and slapped him on the back of the head. "I found a piece of paper in your pants
pocket with the name 'Mary Lou' written on it," she said, furious. "You had
better have an explanation."
“ Calm down, honey”, 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 smacked him again.
“ What was that for?" he complained.
“ Your dog called last night."
