I loved Bonnie. I also liked when Blues Traveler was a Guest Star. :)

(For me) the hands-down winner is Nancy. I loved her sassy attitude. What is cool is the fact that Sandra Bernhard is EXACTLY like that in real life. No acting there.

I luved Patsy & Eddie too. I also like Joan Collins as Roseannes cousin,Ronny(sp?)

Kathy Bowmen
Fred
Bev
Crystal

I really like Nancy, sometimes like Bev and Arnie, but didn't really like Nana Mary, and REALLY did NOT like Prince Carlos. Blech!

Nancy, and Leon.
