The age-old question of which is smaller--snack size or fun size--just got...well, just as confusing.

What kind of snake are we talking about here?  I mean, if it's threadsnake-sized, I'll take fun size, any day.  If it's boa constrictor-sized, then I'll take that.  But once we get up to anaconda-sized, I'd have to wonder whether my chocolate might try to eat me instead.
