I feel anything I pick gives too many false associations, but here goes anyway:
From Terry Pratchett's novels:
Dorfl
Sam Vimes
Alex from Clockwork Orange
Chomski from Barfly (Bukowkski)
Little Big Man
Liz Lemon from 3O Rick, Elaine Bennes from Seinfeld and Sally Albright from When Harry Met Sally.
I like that because I go by Shinytinman on my screen names usually
This was harder than it should have been, lol.
Snoopy
Chandler Bing (Friends)
Andy Dufresne
Darn... that's a hard one... I just can't... I know myself too well to find me really somewhere else... "I am a very complex man with simple issues" or is it the other way around? "a simple man with complex issues"... I don't know... Well, let's try... I am as stubborn as jesus... as passionate and focus as Vlad Dracula... as sinful and degenerate as Giacomo Casanova. Wasn't as bad!!!! But the money is on me... well... at least my money. Good question.
Carmen Sandiego ...love geography
Hermione Granger...cool gal
Elphaba...who I wanna be when I grow up
