Late Night Underground, the totally official unofficial website for Late Night with Conan O’Brien has an amusing (but maybe a bit overlong) video of Mr. O’Brien and his former head writer, Robert Smigel, goofing around on the set. (This comes via TVTattle.)
According to the clip, Mr. Smigel, who recently co-wrote You Don’t Mess with the Zohan, but is probably best known for gifting the world with Triumph the Insult Comic Dog, is not pleased with the persistent promotional "bug" on NBC’s programming. (The "bug" is that translucent logo/ad in the lower left corner of the screen.) After learning how to use a telestrator—the device that allows sportscasters to scribble notes on the screen— Mr. Smigel defaces an NBC promo for Celebrity Circus (the reviews are in: apparently it "sucks") then waxes Perez Hiltonian by scribbling some meta-commentary on himself.
After the segment goes completely astray—telestrations everywhere, PAs wandering in and out—Mr. O’Brien demands that someone "put this on the web." The result is a pretty good video—for me to poop on!
