Lucy and Viv are "birdsitting" Mr. Mooney's pet cockatiel when it escapes its cage and perches on a telephone line outside. To reach the creature, Lucy climbs up on the roof in a grass skirt (her pants split) and rubber swim flippers (for insulation from the power lines). When this fails, the gals resort to buying another cockatiel and try and pass it off as Mooney's beloved bird. (thetvdb.com)
