From Family Guy creator Seth MacFarlane comes American Dad. CIA agent Stan Smith and his wife Francine have two children Steve and Hayley. They also house an alien named Roger and have a pet fish called Klaus.
Roger is a fugitive alien hiding out from authorities who would surely capture him if they knew of his existence. Stan agreed to take him in because he once saved Stan's life.
As if harboring an alien wasn't strange enough, the family's pet fish Klaus can speak because he has the brain of a German man implanted in him.
