Yeah, I'm afraid that the show has already jumped the shark with the near marriage and the pregnancy pact with Will. It's just a tightrope with those characters. If the show doesn't grow, it could become stale quickly, but if it goes too far there will be nowhere else to go but to a series finale. I feel the show will wind down in a season or two unless they find some interesting angle. Hey, maybe Will could have a continuing romantic interest for a season like Grace did. sigh
Anyway, Karen represents several people I know. LOL! She's too fun, but you'd never want to be her designated driver. Believe me.
