### Disappearing diner

A man and a beautiful woman were having dinner in a fine restaurant. Their waitress, taking another order at a table a few paces away suddenly noticed that the man was slowing sliding down his chair and under the table, but the woman acted unconcerned.

Still, the woman dining across from him appeared calm and unruffled, apparently unaware that her dining companion had disappeared.
