Sam looked around, continuing to try and weigh his options. Before today, he had never seriously feared for his life before, but now he was faced with the prospect of freezing to death in the middle of the night, a situation he was certainly unprepared for. "I don't know where anything like that would be. There aren't many things out here with which to keep warm. I mean, we have each other, but...well, with our, uh, current state of dress, that would be, uh, well..." He said, rubbing the back of his neck awkwardly and practically sweating with embarrassment. On the bring side, his embarrassment definitely helped him feel warmer, at least. 

"There's...also that boar over there. I've heard you can...cover yourself in a dead animals...entrails to keep warm, but..." He began, almost gagging at the thought of it. They really did not have many good options, and certainly no comfortable ones.
