To *get* this you have to know that in Japan, the Japanese can say whatever the hell they want and then act shy and it's all good. They are such kind-hearted people that it doesn't come up very often, but when it does, it's definitely a Dear Diary moment. A favorite topic of conversation is how fat Americans are.
Last night I went to Harajuku and decided to try a sweet potato from a vendor. I've heard these guys come calling around my old apartment before (something like the Ice Cream Man in the States, they drive a cart around with a big loud speaker and everyone comes sauntering) but I've never had one before. It was oishii (delicious) and very, very filling. Anyway, when I ordered I told the guy I'd like a small, but he told me he would give me a big because I am big.
Ah, the Japanese.
