The amazing Kresky
The Rockford Files' position as my favorite '70s detective show is of course unassailable. But my favorite fake '70s detective show is now Kresky. This fan site is an incredibly well-done deadpan parody (discovered via Jamie Weinman's excellent blog, Something Old, Nothing New). It's so convincingly done that one can only conclude that the show must have at least aired in a parallel universe, if not in ours.
P.S. I'm totally stealing the name of a minor character I saw in the episode guide to be my new drug dealer name: Good Time Billy Ray. This is, of course, not to be confused with my pimp name, Silky Jones.
