Thorn comes home from work one afternoon and is stopped by his neighbour.
"It may be none of my business, but this afternoon a strange man came to your house and your wife let him in. I peeked through the curtains and saw them making wild, passionate love."
Thorn said, "Was he short, about 5'8"?
"Yes," the neighbor answers, "I believe he was."
"Did he have a droopy eye, and appear drunk?" Thorn asked.
"Yes," the neighbour agrees.
"Then that was the mailman, Jim" Thorn responds "He'll screw anyone!...."
