A husband came home from work and his wife slapped him. "What was that about?" he cried.
"I found a piece of paper in your pants last night with the name 'Mary Lou' written on it," she said, steaming. "You'd better have a damned good explanation."

The next day when he came home from work, his wife slapped him again.
"Now what?" he cried.
"This morning, your horse called!"
