A few weeks ago the So Long As It's Words blog published an informative and amusing post on the origin of the F-word in English. It's more interesting than one might have thought.
The thing I found most interesting, however, is that at least in the 13th century there used to be a place near Nottingham called Ric Wyndfuck de Wodehous. I'm sure P.G. Wodehouse would have admired that name.
