My votes: Shagnasty, Throatwarbler Mangrove, Skald The Rhymer, Guinastasia, Left Hand of Dorkness, Big Bad Voodoo Lou, Hypno-Toad, AuntBeast, Bob Loblaw, and Lobstermobster, among many others that I can’t think of right now. Help me think of some others.
I’m personally fond of Flander. 
Adding to the list, I always liked Mathocist, though I don’t know if he/she posts anymore.
I like Shirley Ujest, Rue deDay, Lion SOB and the many others that are a play on words and phrases. I could never be that clever or original.
I prefer Lobstermonster 
The ones that come immediately to mind are El Cid Viscoso, Exapno Mapcase, Sue Duhnym, SwimmingRiddles. Sue and Swiddles have left the fold, alas.
Don’t poke the bear, Dad!
I can understand why a lot of these are on there, but why is Guinastasia?
I love usernames that are science fiction references, such as teela brown and Podkayne.
No Quiddity Glomfuster? I thought he was a staple of these sorts of discussions!
I just personally like it. The name.
Czarcasm is the best name ever. I like Mathocist a lot too.
Another vote for don’t poke the bear, Dad! I always loved that one.
Ah, don’t forget Hugh Jass.
And I always enjoy ones like nivlac and enipla. The trickiest of that kind is punoqllads.
While we’re here, what’s the meaning of that name which looks like AKSMOTDSK or something like that? I know I’ve spelled it wrong.
I like ComeToTheDarkSideWeHaveCookies. Kickass user name.
I like the plays on words too. Hilarity N. Suze is another good one.
I don’t care about your cat, but she was only a Guest.

I typically hate usernames that’re plays on words but his is easily my most favorite name on the board.

Small British Shop Owner**, which seemed innocent enough, but seemed to creep slowly into your skin. Brilliant.
You just reminded me of The Chao Goes Mu(sp?).
