It was a really tough choice between Peterman and Puddy... both those guys crack me up every time... definite scene stealers. Bob Sacomano was just a comedic device for Kramer--doesn't really qualify as a supporting character, but oh well.
Gotta commend you though... great topic first of all, and good job catching most of the numerous supporting characters. There's only a few missing, but they probably wouldn't garner many votes anyway (e.g. Lloyd Braun--George's Neighbor and assistant to David Dinkins, and Sue Ellen Mishke--the braless wonder).
The Finale (part 1) was on TV tonight and I got kinda misty thinking about how it's the last episode... what a great note to end on too--bringing back all of those characters. In fact, I'd imagine that was your impetus for starting this thread!
Truth be told, ALL of the characters in this poll were awesome. Every single one of them was spot-on and endearing (in their own unique ways).
I'm really hoping they'll do a reunion... maybe in 2008? Let's hope so.
