I would have to say Le Fou! He is such a dolt, that you can't help but like him. Pair that with the fact that Gaston treats him like a dish rag, and he gets my vote!
Another vote for Belle. I may be partial though because when we were at WDW in Oct. we saw her at CRT for lunch and the next day we saw her in France and she remembered DD7 from lunch the day before. She asked her "didn't I see you at lunch yesterday?" It made her day.
