* Mako and Bolin from ''TheLegendOfKorra''. The two of them grew up on the streets, but while the stoic and reserved [[PromotionToParent Mako]] is dedicated to winning the probending tournament and the purse that comes with it, [[TheCharmer Bolin]] is a casual lady's man who loves to have fun.

* In ''AoNoExorcist'', older twin Rin is Foolish while younger twin Yukio is Responsible.

* Partially lampshaded in ''{{Persona 3}}''. When [[CuteShotaroBoy Ken Amada]] joins the team, Junpei assumes a BigBrotherMentor role. Yukari metions something to the effect that Junpei's is like the foolish sibling, while Ken's the responable and mature one.

* Its worth noting that the middle child often falls into this role as well in {{Sitcom}}s. Notable examples of this are ''MalcolmInTheMiddle'' and its titular Malcolm, who is much more responsible than Dewey and, well... just plain smarter than [[RalphWiggum Reese.]]

* ArrestedDevelopment's family tree is a bit too large to fit nicely into this trope, but George Sr. lampshades it by comparing two of his sons.

* Despite being equally talented at fighting, Kim Dong-Hwan and Kim Jae-Hoon, Kim Kaphwan's sons from ''[[FatalFury Garou: Mark of the Wolves]]'', are this, with Dong-Hwan being the Foolish one (a lazy slacker who prefers the Korean nightlife to strict training) and Jae-Hoon being the Responsible one (taking more after his dad in both looks and dedication, to the point of actually inheriting his Hou'ou Kyaku).

* In {{Kekkaishi}}, Toshimori and Masamori are Responisble. Yoshimori is foolish enough for the both of them.

* {{Eyeshield 21}}: Agon and Unsui personify this trope. Unsui is serious, hard working, and a team player. Agon is a lazy hedonist whose also the team's star player.
* {{K-On}}: Yui is the Foolish and Ui is the responsible one

* TheNostalgiaCritic and The Other Guy. Also slightly played with, as The Other Guy is proud to reveal that he controls the Critic like a puppet-master.

** ''MansfieldPark'' does it with brothers -- the foolish Tom and the responsible Edmund bertram; the heroine is in love with the latter.

With humanity almost ruined by Epimetheus, Prometheus had to steal fire and give it to humans to prevent our extinction.

A subtrope of SiblingYinYang. Usually involves an {{Aesop}} about the right way to act, that is to say, be more like the responsible sibling and not the foolish sibling (although the responsible sibling may learn a lesson about "loosening up" and "having fun"). And while the Responsible sibling is usually the elder of the two, the roles can be switched, with the younger sibling being the responsible one. Another possibility is a middle child being the responsible one to his or her older and younger siblings. Also compare TheGloriousWarOfSisterlyRivalry and CainAndAbel.
