Hmm .. sneaky early release .. and you managed to get Thomas Crapper
into the show!
I was about to correct you that Crapper didn't invent the first flush -- I think even the Romans had something like that -- but you mentioned the siphon so I'll accept that. Hang on, though .. it looks like that wasn't his invention either, though he did invent the ball-cock valve.
It's unfortunately a myth that "crap" was named after him (yes, I know you didn't say it was), so it's a case of Nominative Determinism
CRAP is also the acronym for Contrived Ridiculous Acronym Phenomenon, which makes it a contrived ridiculous acronym.
(OK, enough crap from me for now.)
