I really thought the episode "Maggie's First Word" was awesome. Bart was as bad as he was then as he is now and Lisa wasa just as smart. And in the end, Lisa's first word was "Bart", Bart then took her downstairs and told Marge and Homer. Homer asked, "Can you say 'Dadddy'?" and Lisa did what Bart did. She called him "Homer". I thought it was just so weired... they were so close and now they almost despise eachother. Well... fight a lot, anyway. :|
