Justice League Unlimited - 105 - "Kid Stuff"
This episode is worth watching, even if you've never seen TJL before. Kid Batman = hilarity!
Morgaine le Fey transforms Superman, Batman, Wonder Woman, and Green Lantern into 8-year-olds after Mordred uses his magic to remove all adults from Earth. Lots of comic relief in this episode comes from the child-Wonder Woman having a crush on child-Batman, who simply acts like a smaller version of his adult self. Based loosely on elements of the DC Comics events JLA: World Without Grown Ups and Young Justice: Sins of Youth.
