 In some shorts, Joan appears without George, such as "Mouse for Sale", "The Flying Sorceress", "Mucho Mouse" and "Tot Watchers".It could be presumed that George would be working at his office during the settings of these cartoons.George and Joan also appeared in three other Tom & Jerry shorts, "Tom's Photo Finish", "Busy Buddies" and "The Vanishing Duck" (Quacker's last short) and one Spike and Tyke short, "Scat Cats".
