The Finn is pretty much the toughest guy in existance. He rode on horseback to Tibet and met Dalai Lama and gave him a gun as a present. In other words Mannerheim is fucking metal. He is also 30 meters tall and lives eternally orbiting the Alfa Centauri, because our galaxy wasn't metal enough.
Eskimoes only still exists because he condones them. Just one of his many sick jokes that he finds maintain the balance in the galaxy.
