I thought maybe it was also rhetoric. But then I looked through the maintainers forum and read other, older posts on here - in the posts I read, they were really serious. In one post, the lady even talk about how she liked to lick her plate because she had already counted the calories and they were hers!

Btw, licking one's plate does make me giggle - but I don't think there is anything wrong with it (should a plate-licker be reading this).
