Quote from Sophia in Stan's Return
Sophia: Come on in, girls. See, what did I tell you? Dorothy: Ma, what are you doing? Sophia: I was having a meeting with my vacation club. It seems there are a lot of children who like to take vacations without their mothers. Dorothy: Yeah, but... What are you all doing here? Sophia: They never heard of a woman going to bed with her ex-husband. That's him, girls. I can't explain it either.
