"Forgive and forget" joke

The preacher, in his Sunday sermon, used "Forgive Your Enemies" as his subject.
After a long sermon, he asked how many were willing to forgive their enemies.
About half held up their hands.
Not satisfied he harangued for another twenty minutes and repeated his question.
This time he received a response of about 80 percent.
Still unsatisfied, he lectured for another 15 minutes and repeated his question.
With all thoughts now on Sunday dinner, all responded except one elderly lady in the rear.
"Mrs. Smith, are you not willing to forgive your enemies?"
"I don't have any."
"Mrs. Smith, that is very unusual. How old are you?"
"Ninety five."
"Mrs. Smith, please come down in front and tell the congregation how a person can live to be ninety five, and not have an enemy in the world."
The little sweetheart of a lady tottered down the aisle, very slowly turned around and said, "It's easy, I just outlived the bitches."
