Probably The Right Advice

At a wedding the Master of Ceremonies polled the guests to see who had
been married longest. It turned out to be a grey-haired couple in the
corner. The MC asked them, "What advice would you give to the
newly-married couple?"

The lady said, "The most important words in a marriage are, 'You're
probably right.'"

Everyone then looked over to her husband. He said, "She's probably
right."
