Okay, by request:
Michael continues to date British beauty Rita (Charlize Theron), whom he thinks is a preschool teacher. However, all signs point to her being a simpleton woman-child who actually attends preschool with children. At the same time, she may be a spy for her British father Dave Thomas, whose warning to Michael, "How would you like it if someone went after someone stupid in your family?" could be interpreted as threatening Michael's family or warning him away from Rita.
The Bluths get a new lawyer to replace Barry Zuckercorn (Fonzie). His name is Bob Loblaw (say it aloud).
Michael: Well, we're not here to talk nonsense to Bob Loblaw.
And Fonzie's replacement is played by Scott Baio. Get it?
Bob Loblaw: Look, this is not the first time I've been brought in to replace Barry Zuckerkorn. I think I can do for you everything he did. Plus, skew younger. With juries and so forth.
Lindsay lusts after him and uses up the family's retainer when he bills her for her clumsy attempts to seduce him.
George Sr. participates through Larry Mittleman (Super Dave Osbourne), a "surrogate" who wears a camera in his hat. George Sr. watches from his house arrest and Mittleman repeats everything George Sr. says to the others, including "Where you going? Where is the surrogate going? Stay there. I want to see what he's going to say. Don't leave."
The main story has to do with Michael lying to Rita and telling her that he has no family, because he's ashamed of them. The family, in turn, tries to do something nice for Michael by inviting Rita to their party, but end up accidentally knocking her out and drugging her to forget the incident. Gob's use of roofies (a forgettiness aid magicians refer to as "Forget-Me-Nows" to protect their secrets) retroactively explains a joke in the previous episode in which Gob offers a Bluth employee a mysterious pill after he's witnessed the secret of a magic trick.
Meanwhile, Maeby is dating Steve Holt, and George Michael's comment that older guys expect more sexually makes her nervous.
Maeby: That Steve sure knows how to please a lady.
George Michael: Good. I was hoping he would be gifted sexually. I guess it makes sense, you know, older guys expect certain things.
Maeby: They do?
George Michael: What a fun, sexy time for you.
George Michael learns that Steve is their cousin but struggles with whether to tell Maeby, since bringing that up as a negative might prevent him from pursuing her later. Eventually Maeby gives Steve Holt a roofie to trick him into thinking they slept together, although this is after Steve learns she is his cousin and no longer wants to have sex with her.
Also, Buster accidentally re-enlists in the army by accepting a medal, Tobias tries to get Buster to stand up for himself, and George Sr. tries to escape house arrest on a deckchair held up by balloons.
And Tobias reminds Lindsay that he was "a professional twice over--an analyst and a therapist. The world's first analrapist."
Tobias: Here, take my business card.
Tobias: No, no, it’s pronounced a-nal-ra-pist.
Buster: It wasn’t really the pronunciation that bothered me.
