 That's not a good one. A mom doesn't know that that's a dummy in a sound system? Is the mom brain dead? I'll say this. If somebody is laughing at a movie from the 70s or 80s now, as they did back then, I think it should be bonus points for that show. If they're not laughing, I don't think it should be a knock on it. You don't think you could sit down and watch an episode of The Jeffersons right now? You will laugh. No, you will not.
