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 during a small party. He was a bit foggy after having a drink or two.
He said loudly, "The greatest years of my life were spent in the arms of a woman who was not my wife!"
The wife went red with shock and rage.
Standing there for 20 seconds trying to recall the second half of the joke, with the guests not saying a word, the manager finally blurted out
"... and I can't remember who she was!"
