[Cadaverous Pallor]

I have a feeling there are lots of groups on this island.

It'd be funny if they actually got the actors to lose weight...but as anyone who watches Survivor can attest, a truly deserted person starts to look really thin really quickly. If they've hit day 48 and everyone's still plump, it wouldn't make any sense to make them start losing weight now - the illusion is already blown. Whatever, we just have to pretend.
