Marge: Oh Maggie, when are you going to talk?
Lisa: Well, don't push her. Remember, it is better to remain
silent and be thought a fool than open your mouth and
remove all doubt.
Homer's brain: What does that mean? Better say something or they'll
think you're stupid.
Homer: Takes one to know one.
Homer's brain: Swish!
