Margaret wanted to marry Dennis. This was a running gag in both the comic strip and the television show. She pushed a baby carriage through the neighborhood. "Playing house" was something she pressured Dennis to do. When Dennis needed a penny or two, she gave it to him but only after he promised to play house with her. If he turned her down, she would hit him with one of the rag dolls in the baby carriage and prance on her way.
