A tipster informs us that the Guild's roaming, set-disrupting WGA Strike Force, armed with whistles, bullhorns, and—always a a classy touch—a saxophone, just successfully shut down a Mad TV location shoot in Hollywood's DeLongpre Park, where the show was trying to get footage for a sketch called "The Worst Magician in the World." With the unkillable series featuring no recognizable stars to take hostage for the cause, however, the marauding writers will have to settle for the satisfaction of having temporarily hobbled Fox's ability to profit from the exploitation of David Copperfield's misery.
