One night an elderly couple was sitting on the front porch in their rocking
chairs. All of a sudden, the old woman leaned over and knocked the crap out
of the old man. The old man, laying on the ground asked, "What was that for?"
The old woman answered, "That's for having such a small sex organ all these
years." So the old man got back on his rocker again. After a few minutes the
old man leaned over and knocked the crap out of the old lady. The old lady
said, "What the heck was that for?" The old man replied, "For knowing the
damn difference."
