Assisted by ticket-taker Bimbo the Dog and product-demonstrator Koko the Clown, Betty Boop stages a "Big Invention Show." Highlights of the program include a pig-powerd pipe organ, a Rube Goldberg-style spot remover, a cigarette snuffer, a soup silencer, a sweet-corn regulator, and an egg-frying device, replete with optional hen and rooster. Betty herself demontrates a most unusual voice recorder with a performance of "Keep a Little Song Handy." The show's Number One attraction, a VERY powerful self-threading sewing machine, knits up the proceedings quite nicely. ~ Hal Erickson, Rovi
