Stan Smith has come up with a lot of stupid ideas over the years on 'American Dad' (Sun., 9:30PM ET on FOX), but this may well be the stupidest. In a nod so deliberate to 'Avatar' they came right out and admitted it, Stan decided to try and spend more time with his son Steve by becoming a teenage girl.

This was after he realized he'd missed every major moment of Steve's life so far and Francine told him that as a teenager, hot girls were all Steve was interested in. So Stan became an avatar, voiced by Sarah Michelle Gellar, in order to hang out with Steve.

Things got weird though when Steve wanted to up the romance factor. Fearing he was going to lose Steve, Stan decided to commit and agreed to have sex with his son via the avatar. Yes, you read that right. And if Francine hadn't intervened to battle him off, things would have moved from very uncomfortable to incredibly disgusting.

Stan just needs to do what all parents of teenagers do. Wait until they're adults and are willing to talk to you again. Of course, since this is an animated family, he'll probably be literally waiting forever for Steve to grow up.
