I remembered some bit about Morris dancers from Blackadder, so was quite amused to actually see some at a small town event in Devon on my one and only trip to England.
Besides Dr. Who and Cthulhu scenarios, one could work in some Morris dancers into scenarios based on 18th Century smugglers or highwaymen, 17th Century swashbucklers or ECW, the X-files, UFO, the Avengers, or Dad's Army... and Blackadder, of course.
