A man and woman were having dinner in a fine restaurant. 
   They were gazing lovingly at each other and holding hands. Their waitress, 
taking an order at a table a few steps away, noticed 
   the man slowly sliding down his chair and under the table, but the woman 
acted unconcerned. 

  The waitress watched as the man slid all the way down his chair and out of 
sight under the table. yet the woman looked 
  calm and unruffled, apparently unaware that her dining companion had 
disappeared. 

   The waitress went over to the table and said 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."
