The slang term for "crapper" originated from the American servicemen stationed in England during World War I where they saw his name on cisterns and used it as army slang, "I'm going to the crapper."
Maybe that's why the toilet is also referred to as the "john".
LOL! This thread has been fun and informative. I think you are probably right - always wondered where the "John" came from, and that is probably the origin not only of "crapper" , but probably the term "crap" itself!
