I guess the burning of an effigy of Guy Fawkes every November the 5th all over the UK doesn't count...:^)
Sadly a custom now much in decline. In the last decade or so it's rapidly been replaced in the public conciousness by Hallowe'en, a festival which was hitherto almost entirely unrecognised here in Britain. Largely a result of American cultural imperialism, it has to be said...:). My generation had to have 'trick or treat' explained to them the first time urchins came knocking on the door a few years back...before then it was always 'penny for the guy?'
