Batman, Wonder Woman, and the Flash are all crack crimefighters, but when they get home at the end of the day, they still have to pay the bills, do housework, and unwind like any other person.
Caleb Paullus' Super Not Super is a series of brief photo comics exploring the not-so-superheroic trials and tribulations of caped crusaders. Batman finds even he is not immune to the economic meltdown, the Flash fails at physical intimacy, and Catwoman unwinds with a little *ahem* catnip. Sadly, Wonder Woman and Supergirl couldn't be given anything more interesting to do than household chores.
