The opening scene in this episode is classic Will and Grace but doesn't quite redeem the rest of the episode.
Will acts completely unprofessional at the office, acting more like a teenage boy as class president of the 8th grade than a lawyer (which in the past he'd always had a ego about). Nor do I believe Karen would ever live out of a limo. She's too cunning to not have some money stashed away.
Inconsistency aside, the core cast did it's usual great job together, but some of the writing simply falls flat.
Mr. Stein is written so painfully that it's awkward and uncomfortable to watch. But Gene Wilder does what he can with what they gave him. Some of his scenes go on way too long.
Easily the best scene of the episode is in the limo while Karen, Rosie, Jack and Grace try to sleep. Karen: "Grace, that had better be your penis." Grace: "It's a thermos, but thank you." is a great joke with an even better payoff. And the comment about the three-way marriage with Maury Povich and Connie Chung? Classic Karen.
