The Boys in the Band

JT gives Al's band a name and becomes their manager. He gets them a gig at a bowling alley that Frank just finished remodeling. The owner of the bowling alley is inflexible, though, and when the other four girls in the band catch the flu, JT has to recruit Karen and Dana. Because he can recruit noone else, JT and Cody end up singing with the band dressed as girls. During the first song, the audience discovers JT and Cody are men and Carol steps up to save the day. A mouse that ran from the beauty salon to the house is scaring everyone except Frank. Frank is unable to kill the mouse, however, because his family does not think he should kill an ""innocent"" creature.
