The lamb... (possible spoiler)
So he gets a fifty pound shank of lamb. It's frozen solid... A few hours later after walking arounnd outside with it, it's melting and leaking blood already. It wouldn't have even have begun to thaw let alone be at the point where blood was leaking all over the place, especially being outside in the cold.
This makes no sense. It's winter in the movie, and on top of that, it takes at least a full 24hrs or more to thaw even a 25 pound turkey.
