I've always found it odd that the pronunciations of the words "liquor" and "liqueur" seem to be reversed. Liquor, pronounced "lick-er", is spelled like it should be pronounced "lick-or". Likewise, liqueur, which is pronounced "lick-or", looks like it should be pronounced "lick-er".
I was once a bartender and this is the kind of stuff I would think about on slow days.
