When REALLY not to use "u" after "q"

The capital of one of Canada's northern Territories, Nunavut, goes by the euphonious name Iqaluit (it used to be called Frobisher Bay, much less musical). In Inuktitut, Iqaluit means "many fish". Unfortunately English spelling has a habit of putting a "u" after the letter "q", so English speakers commonly misspell Iqaluit as Iqualuit (in fact I just saw that spelling in yesterday's Ottawa Citizen). Indeed, in September 2009 the Prime Minister's Office used this misspelling repeatedly in a press release, causing a great brouhaha when the Nunavut Language Commissioner pointed out that "iqualuit" means "people with large unwiped bums" (that's bums in the "buttocks" sense, for any American readers who are confused). DEFINITELY a mistake you don't want to make.
Another Inuktitut borrowing into English with a "q" not followed by "u" is qiviut, or the fine underbelly hair of a muskox. There's a bit of trivia to impress your friends with.
