None. I've never watched family dad,but it's so weird because the first time I ever heard of it was today! Someone was talking about the american dad show making fun of HANSON. BOO!
So, I automatically don't like american dad. lol Jk, but I don't think I'd find either of them to be funny. I know I don't like family guy. I don't get that kind of humor and find a lot of it to be distasteful.
