The audience

A famous speaker who came with his wife addressed the audience.
"The best years of my life were spent in the arms of a woman who wasn't my wife!"

The audience started staring at his wire in silence and puzzle.

Then speaker added with affection, "And that woman was my mother!"

Audience was touched and the speaker achieved what he came to do, l
The corporate big executive totally dependent on subordinates,
tried to crack this joke at a party in his home. He was tipsy with drinks.

He cut the story he heard announced loudly to the guest, "The greatest
years of my life were spent in the arms of a woman who was not my wife!"

The wife went crazy and about to crack the big glass dish on husband's head.

The husband kept scratching his head, looked at his wife and then
announced, "Damn, after the drinks I don't remember who she was."

He could never paste the story back to his wife convincingly enough.
