A waitress who is serving at the next table, notices the man slowly sliding down the chair, until he disappears under the table, whilst the woman appears completely unconcerned, and appears not to have noticed!
The waitress, concerned, went over and discreetly whispered to the woman, “Pardon me ma’am, but I think your husband has just slid under the table!”
She replied, “No, actually, he’s just walked in the front door!”
