Lewis Turns Twenty-Fun

For Lewis' twenty-first birthday the Kellys plan the usual kid's party in the pizzeria; Mary has coined and even registered the term 'twenty-fun'. Tom convinces Chris that even Lewis must be ready for a more manly celebration at 21, so they first plan a more frat-style evening at a bar. Meanwhile, Mary is green with envy when Susan lands the only job she was ever fired from; hostess.
