A man and a woman were having a quiet, romantic dinner in a fine restaurant.
They were gazing lovingly at each other and holding hands. The waitress, taking another order at a table a few steps away, suddenly noticed the man slowly sliding down his chair whilst the woman stared straight ahead.
The waitress watched as the man slid all the way down his chair and out of sight under the table. All the while the woman stared straight ahead.
The waitress, thinking this behaviour a bit risqué and that it might offend other diners, went over to the table and, tactfully, began by saying to the woman "Pardon me, ma'am , but I think your husband just slid under the table."
The woman calmly looked up at her and said, "No, he didn't. He just walked in the door."
