Ryan wants to start a club. An Only Child Club. He knows that as an only child he doesn't always have the same experiences as some of his classmates. He recruits two similarly deprived friends who join him in an experimental few days of constant bickering, fighting over who gets the free gift from the cereal box and spending a whole day making a model, only to have it destroyed. Having had a taste of what it's like to have siblings, the club is happily disbanded and the trio realizes that friends are nearly as good as having brothers and sisters - and often less annoying!
