This week's FG went in a weird direction. The 28 Days Later scenario was really interesting. Loved the callbacks to old gags and how their amnesiac minds changed their views on those jokes. Also loved the pretty decent character work throughout the episode, with the Peter/Brian friendship reinforced.
The ending was another one of those Stewie simulations. And in this case, it worked pretty well.
Joe: Hey, I found my house. Turns out my name is Joe Swanson. And I found this police uniform in my closet. Do you know what that means? I'm a stripper!
