Funny. We brought a Superman one of those for my four year old son a few months ago.
He is now banned from wearing it at school because him and his friends would play "Superhero" with himself as Superman and the other boys as the crooks. The main part of the game involved Superman (i.e. my kid) beating up the crooks (i.e. the other kids). Apparently they got a little rowdy, as little boys tend to do, and someone got hurt. Hence, the ban.
He still wears it on the weekends an awful lot though...
