A dinner party

At a dinner party, the speaker who was the guest of honor was about to deliver his speech when his wife,

Who was 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,

“It looks like your wife has sent you a kiss for good luck. She must love you very much.”

The speaker replied, “You don’t know my wife.

The letters stand for “Keep it short, stupid.”
