Speaking of Conan O'Brien (and we just were, remember?) - here's a failed pilot he wrote with Robert Smigel called Lookwell starring the great Adam West.
Lookwell (even the title is funny) aired once on NBC, and then took on a level of infamy among Hollywood insiders and tape traders. A few years ago, it re-aired on the (now defunct) Trio network - and is currently available on YouTube. (Supposedly, this is a slightly different version of the episode that aired on NBC - but much of the humor is still intact). Enjoy!
