Laughter and applause.
A week later, a top manager trained by the motivational speaker tried to crack this very effective joke at home. He was a bit foggy after a drink. He said loudly to his wife who was preparing dinner, "The greatest years of my life were spent in the arms of a woman who was not my wife!"
The wife went; "ah!" with shock and rage. Standing there for 20 seconds trying to recall the second half of the joke, the manager finally blurted out "....and I can't remember who she was!"
By the time the manager regained his consciousness, he was on a hospital bed nursing burns from boiling water
Moral of the story: Don't copy if you can't paste!
