Does anyone else think our (Canadians) insistence on putting u's in words like "favour" and "honour" is stupid. Maybe it is just one of those things we do to delude ourselves in to feeling unique? Us Canadians do a lot of things right. Getting rid of the penny? Right. Not having single dollar paper bills? Right. Not having our money just one color? Totally right. Having bagged milk? You bet that's right. But this whole putting U in things never sat well with me. Kudos to you America for cutting the U.
It's the British spelling. Spelling these words with the letter U is more common, and arguably more correct and less *special* than you seem to think - globally-speaking. Americans are the odd man out. Canadians are just more in line with the rest of the world.
