Ripley and Skinner of course......
Seriously speaking, I second the Jane Krakowski school, her "Funny Honey" would stop the show. Actually, I'm inclined to think that if she hasn't played it yet, she probably won't. I can't imagine the Weisslers wouldn't have asked her in all this time.
Sarah Jessica Parker could be interesting...maybe.
I'd also like to see Sara Gettelfinger as Roxie opposite Rachelle Rak as Velma.
And of course Megan Mullally as Roxie.
