Ugly Bastard - Cartoon dads are just hentai ugly bastards that stay around to raise their kids

But you see, the fact that they are committed and eventually become good dads makes the "bastard" half false, so that makes it go from "ugly bastard that got away with it" to "ugly but good guy teaching kids that even ugly people can have a happy family and life", so that makes it do a 180 turn and go from chaotic to wholesome.
