Contrary to popular belief - the crapper was not invented by Thomas Crapper - it was invented 50 years before he was born. Thomas crapper was a plumber and he may have installed some. Crapper comes from the English word CRAP which was any discarded refuse, junk, remains, etc. CRAPPER was a term invented by American soldiers during WWI who were stationed in England.
My tummy hurts - I must get rid of some crap. May I please use your crapper?
