There was this show on one time, on Discovery I think, and there was this guy right, and he was on a desert island. Well he didn't want to be on this desert island, so he built himself a raft and set off to find mother England, but he ran out of potable water. Luckily, he had collected some bird droppings and shitwater, so on this television program, he gave himself an enema (to avoid the gag reflex) for the purpose of re-hydration. I've been a fan ever since.
Here he is now
