I seem to remember that being a hot topic of discussion back when the movie was released. Not that Winslet was fat, but that she was a little heavier than most leading ladies.
Which, to me, is actually about perfect. Some of those chicks now... too damn skinny. No shape. That's why I hate how "curvy" is starting be used as this denial-euphemism for "fat". Because it's NOT, man.
Anyway, back to the topic at hand: the riff was outstanding. Probably the funniest one you've done. I reached a point where I couldn't even laugh anymore, it was just a prolonged gasp.
