Muffy's Bat Mitzvah

T1, E13: Muffy's "new wave" bat mitzvah celebration stands to be the "in" social event of the season for virtually all of Weemawee High, except for Lauren, Patty, Johnny and Marshall who have all been mysteriously omitted from Muffy's exclusive guest list. Popular new wave recording group DEVO, in its primetime television debut, performs the single "That's Good" from their latest album "Oh, No! It's DEVO" at Muffy's bat mitzvah party.
