A popular motivational speaker was entertaining his audience. He Said : "The best years of my life were spent in the arms of a woman who wasn't my wife!" The audience was in silence and shock. The speaker added: "And that woman was my mother!"

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!
