At a dinner party, the speaker who was the guest of honor,
was about to deliver his speech when his wife sitting at the
other end of the table, sent him a piece of paper with the
word “KISS” scribbled on it.
A guest seated next to the speaker said, “Your wife has sent
you a KISS before you begin your speech. She must love you
very much.”
The speaker replied, "You don’t know my wife. The letters
stand for “Keep it short, Stupid.”
