Chuck was on a deserted island for four years with no suggested means of manicuring his nails, but when you catch a few glimpses of them as he's preparing to leave the island on his raft they are perfectly neat and trim. Also, he has to tackle some pretty ferocious waves when he leaves in order to get out into the open ocean, but when he first arrives at the island on the rubber raft, he floats up to shore as if he were drifting in a swimming hole. No sign of wave damage anywhere, he wasn't capsized or even woken. Strange, huh?
