Roxy Rumbles
Episode Synopsis: Roxy quits the Misfits because they tease her about her about being illiterate. She stumbles upon a million-dollar lottery ticket, and heads back home to Philadelphia to show off to everyone that she made it. She puts on a street festival that runs amok and takes away the publicity from Jem's Rock out Illiteracy concert.
