The MacDonalds hire Linda to baby sit their 3 children: Bobby, Cindy, and Punkin. Linda drags Sue along to help, which she badly needs, as Cindy's bubble bath threatens to overfoam the house, Bobby turns into a toilet-papered mummy, Punkin finds a phone to do her numbers on, and suddenly pizzas arrive plus firemen, as well as Bobby's best friend and his irate mother... and... well, eventually they all live happily ever after.
Un-Sittable first premiered at Conant Junior High School by their eighth grade theater class in 1975.
