A man and a woman are having dinner in a restaurant.
Their waitress, taking another order at a table a few paces away, spots that the man is slowly sliding down his chair and under the table, with the woman acting unconcerned.
As the waitress watches, the man slides all the way under and out of sight.
Still, the woman dining opposite him appears not to notice.
Finally, the waitress comes over to the table and whispers discreetly to the woman, “Pardon me, ma’am, but I think your husband just slid under the table.”
“No, he didn’t,” the woman calmly replies.
“He just walked in the door.”
