If I'm not mistaken, the episode you're referring to is a dream. None of it is real.some of the cases are so extreme that I laugh, like some guy bleeds from his eyes, then he jumps off a balcony, and his head explodes and then he pisses ice or something, then house will learn a valuble lesson from the comical scenes with one of his regular patients that doesn't mean anything exept to be a means to the solution to the main cases problem.
