“PES” is Adam Pesapane, and since 2002, he’s been creating wonderfully witty stop-motion shorts, full of visual puns and wordplay. Last December, he released Submarine Sandwich, the final film in the trilogy that began with Western Spaghetti. in 2008. The middle film, Fresh Guacamole, was nominated for the Academy Award for Best Animated Short Film. At just 1:40, it’s the shortest short ever nominated.
