Marge Gamer -

Marge feels the shame of the other parents at a PTA meeting when she reveals she doesn't have an E-mail address, so she goes online, and soon gets involved in an online role-playing game, only to discover the most feared character is Bart - who ends up killing her character accidentally; Homer becomes a soccer referee for Lisa's league, only for him to give her a red card after she takes advantage of him by flopping one too many times on the field (only for special guest voice Ronaldo to set the record straight)
