There was this eighty-year-old man who was seeing the doctor for a checkup. The doctor asked why he needed the checkup. The man was getting married next month to a girl 60 years his junior. The doctor tried to talk him out of the marriage, and it didn’t work.However, the doctor suggested, „If you want your marriage to last, I say you at least take in a boarder.“The old man agreed.The old man didn’t see the doctor until they met at a fund-raiser a year later.The old man says, „Doc, congratulate me, my wife is pregnant.“ „That’s good news,“ said the doctor. „I knew the boarder would help.““Oh,“ said the old man with a wicked grin, „and the boarder’s pregnant as well.“
