Bear Grylles show on discover is great to watch. Whether he stays the night in a tree or a 5 star hotel doesn't take away from what he does on the show. He ate a bug from inside the bark of a tree. He bit into it and the thing exploded with puss. He still ate it though. Later on he was climbing up a vertical cliff face he got the runs from eating said bug. He pulled his trousers down, while the guy still filmed.
The other guy is Survivorman. He has no crew with him and by the look of him in the morning I would say he sleeps in the bushes. Tough TV!!
