Fat boys (Disney Channel staple). Musical episodes that're usually talentless. Unattractive guys who have hot wifes or girlfriends. Nasy mothers-in-law (Except on "The Munsters," where it was the father-in-law, who was a pretty nice guy). Parents-in-law who don't get along with their kid's spouses or their kid's parents-in-law. Kids who have a parent for a parent-teacher conference (sings: "Substitute. You for dad. Substitute. Adults get mad.") parents who meddle in their adult children's lives. People who destroy other people's stuff and then attempt to replace it, usually with disastrous results). P.S.: Friends used the "Kid Trick" staple when they aged Ross's son Ben by one year.
