Hitler Banned on Wii
If your last name happens to be “Hitler” then your parents must have really hated you. Nintendo hates you, too, as anyone trying to login to the Mii service using that name will be greeted with an error message saying such names aren’t allowed on the service.
However, if you really want to use that name on your Mii, try variations like ‘Lil’ Hitler’ or maybe even Hitlii.
