Steve and Kate were having dinner in a very posh restaurant. Their waitress, taking another order at a table a few paces away, noticed that Steve was slowly sliding down his chair under the table while Kate didn't seem to notice.
Their waitress watched as Steve slid all the way down his chair and out of sight under the table. Still, Kate appeared oblivious.
After the waitress finished taking the order, she came over to the table and said to the Kate,
"Excuse me, madam, but I think your husband just slid under the table."
The woman calmly looked up and replied firmly, "Oh, no he didn't. In fact, my husband has just walked in the front door."
