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