Hom sir is the old timey version of homsar. He looks virtually the same apart from he's wearing shoes instead of sandalls his hat is a top hat and his top reads "Hom sir's fine print shop" suggesting he bought that and he wasn't actually hom sir.
He speaks the same except a little bit deeper.
His first appearance is in the old timey cartoon "The lonely man" where hom sir is found sitting by himself with a small shrub. saying "mah freend sen your cad gaige will appear any second." the others think he's crazy so they look after him, while sir strong bad will try to put hom sir back on the street.
