January 27 is Thomas Crapper day, commemorating the man who invented the ballcock, which is that float-triggered flushing mechanism in your toilet. Despite popular misconception,   Thomas Crapper did not invent the toilet itself- flush toilets were around for about 250 years before Crapper was born.

The term "crapper" in reference to the toilet probably relates to Thomas Crapper, but the word "crap" came into the English language hundreds of years before Crapper was born.
