As Alicia was getting to know Michael and his family, she was very impressed by how much his parents loved each other.
"They're so thoughtful," Alicia said. "Why, your dad even brings your mum a cup of hot coffee in bed every morning."
After a time, Alicia and Michael were engaged, and then married. On the way from the wedding to the reception, Alicia again remarked on Michael's loving parents, and even the coffee in bed.
"Tell me," she said, "does it run in the family?"
"It sure does," replied Michael.
