What's geekier than KLF's 1988 "Doctoring the TARDIS," a novelty mashup of the theme to British Sci-Fi series "Doctor Who" and Gary Glitter's "Rock and Roll (part 2)" that went to #1 on the UK charts?
What about Dean Grey's 2005 mashup of KLF's 1988 hit with Green Day's "Holiday"?
Take one instrumental TV theme, combine one novelty rock anthem primarily used now for NBA team entrances, and Green Day's growly punk pop energy. Might be geekier, but it actually improves upon KLF's version.

(from Dean Grey's American Edit album featuring mashups of Green Day's entire American Idiot album, which lasted an entire 10 days on the Web before the lawyers from Warner Brothers served up a cease-and-desist order. Boing Boing was all over the American Edit event, but I ignored it, not being a fan of Green Day. So, consider this a late entry.)
