This is exactly how people end up believing in extra terrestrials and what nots. Now please tell me one thing from what I have learnt so far from "X-Files" is that aliens never look green or have big eyes or anything else like that so why in the world would do they use a separate toilet. They mostly come in human forms, don't they? And honestly I think the only people using the alien toilets are those who want to see an actual alien. Yes, you guessed it right, they are humans. Haahahaahaha
