American Dad: Season 5, Episode 4

5 - 4: Brains, Brains, and Automobiles

When Hayley and Steve leave for their respective summers of fun, Francine looks forward to her newfound alone time with Stan. There's only one problem: Roger is still living in the attic fighting for every second of attention he can get. When Francine teaches Roger to be self-sufficient, he finally gets a place of his own. Stan fears that he will bore Francine into leaving him and cooks up a scheme to bring Roger back to the house and liven things up. Meanwhile at camp, Steve and his pals fall prey to a scheme that doesn't quite have the effect they were hoping for.
