Lest you forget about comedy during the off-season, SF Sketchfest is hosting its Summer Social at the Castro, featuring three film screenings with a quirky array of special guests. First, watch The Muppet Movie with guest Dave Goelz, better known to you as Gonzo (and Professor Bunsen Honeydew). Find out if Gonzo and Camilla the chicken had any off-screen romance. Then there’s Twilight: Eclipse, screened at 4:20 p.m. by famous pot-smoking comedian (the comedian savvy enough to turn pot into his brand, anyway) Doug Benson and his surprise panel of guests, who will undoubtedly skewer the new teen vampire classic! If ever a movie deserved to be roasted, it’s definitely one of the Twilight films. A 15th anniversary screening of Office Space caps off the night, featuring stapler-hoarding Milton (Stephen Root) as the special guest to be subjected to a Q&A. Find out if Milton and his stapler had any off-screen romance.
