Joanie and the Hepcats
In the two-part Married with Children episode "Kelly Does Hollywood" (Part I aired November 10, 1991; Part II aired November 17, 1991), teen Kelly Bundy (Christina Applegate) gets her Chicago public access trash-talking discussion show, Vital Social Issues 'n' Stuff with Kelly picked up by a network.
Her house band Joanie and the Slashettes, are transformed by the NBS network this besweatered, long-skirted accordion trio, whose single-word song is "milk!"
Then the show gets cancelled. Alas, not lowbrow Fox sitcom Married With Children, but Vital Social Issues 'n' Stuff with Kelly.
