Now this is American Dad at its very finest.
Roger is the center of this story and we get some nice flashbacks of how he ruines Stan's things/moods/life, while all the time being protected by Francine.
Well, she's an enabler and Stan proves that to her.
While Francine fakes Roger's kidnapping in order to win Stan's attention, Stan knowingly plays along, but not as the other two had hoped to...
Anyways, even though the story IS funny and nicely told (especially the hilarious twist during the 2nd half, where Stan reveals he knew about the faked kidnapping all along), it's the amazing amount of perfectly timed jokes that make this episode one of the best so far.
Be it Roger's attitude or Steve's ambitious background-dancing, the jokes just keep on coming non-stop in this one.
