That reminds me, I must resume work on my story in which Xander is the son of Hercule Poirot and Xena. Inspired, of course, by some of the more ludicrous (but not intentionally funny) 'Xander's real family' stories at 'Twisting the Hellmouth'.

I would, however, rather read a story in which Buffy is the long-lost daughter of Mustrum Ridcully and Granny Weatherwax, or of John and Holly McClane, than one in which the author decrees that 'Buffy' is a nickname and her real name is Elizabeth.
