Superman and Batman are not getting on well with the Super-Sons. So, at Clark Jr. and Bruce Jr.'s suggestion, they all head for an "Encounter Camp" to work through their problems and "break down their barriers" and "heighten their awareness." Heavy, man.
Anyhoo, guru/spiritual adviser/head hippie Dr. Zamm introduces them to the next step in "finding themselves":
Clark's reaction is just so priceless:
You can take the boy out of Kansas, but you can't take the Kansas out of the boy. I'm not sure if he's more put off by the dancing itself or the proximity of other men...
But they paid for the weekend, so they go ahead and get footloose:
That is the scene I most wish I could see animated in one of the direct-to-DVD DC "movies." Seriously, aren't the Super-Sons next in line? Wouldn't you rather see this scene in convenient cartoon form, rather than Dark Knight Returns?
