God, I loved that beginning. The Honeymooners, The Dick Van Dyke Show, The Brady Bunch, Cheers...too bad the original theme music for each show wasn't used. It'd have been even more fun.
Actually, the whole episode was great. Helped restore my faith after the truly bizarre ep last week. And although there was kind of a message, it wasn't heavy-handed, and you got the feeling that the ep was based on a funny idea, not a political message. So it was fully enjoyable. 10/10.
