Tom comes home from work one afternoon and is stopped by his neighbor, "It may be none of my business, but this afternoon a strange man came to your house and your wife let him in. I was mowing grass between our houses and I happened to look in your window and I saw them making wild, passionate love."
Tom asked,"Was he short, about 5'8?"
"Yes, "the neighbor answers, "I believe he was."
"Did he have a droopy eye, and appear drunk," Tom asked?
"Yes," the neighbor agrees.
"Then that was the mailman, Jim," Tom responds. "That guy will screw anything."
