Not their greatest effort. The plot felt very familiar, with the whole "impromptu fake marriage" thing going on. And Tank Bates's replies to all of Stan's defenses for Terry being gay could be seen coming, especially since they did so many of them in a row. And Stan saying "____'s all right...." in a laid back manner was funny the first time but lost its punch after two more in the same 30 seconds.
I hope American Dad doesn't suffer now that the Cleveland Show's in the heat of production.
