For me, I suppose I've always liked Han Solo.
I remember seeing Episode V in the theatre, and it seemed Everything Han said was gold, Here's my favorite exchange:
Solo: Well Princess, it looks like you managed to keep me here a while longer.
Leia: I had nothing to do with it. General Rieekan thinks it's dangerous for anyone to leave the system until they've activated the energy shield.
Solo: That's a good story. I think you just can't bear to let a gorgeous guy like me out of your sight.
Leia: I don't know where you get your delusions, laser brain.
[Chewbacca laughs]
Solo: Laugh it up, fuzzball.
I think this was, for me at least, a defining moment for Han's character, and it is the first movie quote I memorized as a kid, and used in normal life - I don't know how many of my friends had to suffer through my squeezing the "Laugh it up, Fuzzball" line into as many conversations and situations as possible.
