YEa they did. It is because Sanji is an awesome cook with a cigarette. and have you noticed in One Piece all the weird things are on the left where as in other animes they are on the right? I think thats awesome.
also it is Monkey D. Luffy, Roronoa Zorro, Choppper Chopper, Sanji, Smoker, Nami, and that other girl I forget the name of. I missed a lot of last names but these are the real names. it is not Zolo. that really pisses me off.
