As for American Dad, I would be perfectly happy if they found a way to work Roger into Family Guy and just cancel American Dad. Roger is the only one on that show I can stand.
I know it's often debated if it's a spinoff. I see the differences, but I see the similarities aswell. Both have a mother, father, and three children. In both, the father hangs out at a bar. That's not to mention how many episodes look like the other's. IIRC, both have had an episode where they become their own country.
