Slated to appear at tonight's SF Sketchfest Tribute to Conan O'Brien, the ginger talkshow host has postponed his SF gig:
SF Sketchfest's a href="http://www.sfsketchfest.com/schedule/">breaks the bad news:
Due to the uncertainty surrounding the future of The Tonight Show, Conan O'Brien will have to postpone his appearance. Ticketholders are advised to keep their tickets and will be notified when the event has been rescheduled.
If you recall, Jay Leno, a horrible human being, failed to to grab viewers' attention with his painful foray into prime time TV. So, after promising the far superior O'Brien The Tonight Show, which he hosted for a few months, Leno took part in rescinding the offer because, inexplicably, he wants to remain on TV. And because he's an talent-free fleck of dried-up fecal matter.
SFist will update you if/when the show is rescheduled.
