FRANK and Julie are having dinner in a fancy restaurant. Their waitress is taking another order at a table nearby, but notices that Frank is slowly sliding down his chair under the table. Julie appears unconcerned by this unusual occurrence.
The waitress continues watching as Frank slides all the way down his chair and under the table, out of sight. Julie still appears apparently unsurprised at this.
So after the waitress finishes taking the order, she comes back over to the table and says to Julie: “Excuse me madam, but I think your husband just slid under the table.”
Julie looks back at her calmly and replies: “No he didn’t. He just walked in the front door.”
