There certainly seem to be a plethora of toilet pictures out there! Here is one from Legoland in Winsor, England. Which brings up the question: "There is a plethora of toilet pictures" or "There are a plethora of toilet pictures"? Fowler states that "Nouns of multitude are treated as singular or plural at discretion - and sometimes, naturally, without discretion." Whoa, that's a big help!
So, Strange-Trippers, what think ye?
