An elderly man turns to his wife and asks if she’s ever cheated on him.
“I love you,” she says, “but I must confess. I’ve been unfaithful to you three times.”
“What?” yells the man. “When?”
“The first time was when we were denied a mortgage,” she explains. “I went to see the banker, and I persuaded him to give us the loan.”
“The second time you were ill and we had no insurance to cover the medical bills,” she says. “I went to the doctor and convinced him to treat you for free.”
“And what about the third time?” the husband demands.
“Remember when you ran for mayor,” the wife begins, “and you were behind by 300 votes?”
