During the "On the next Arrested Development..." gag, most of the situations are allusions to the first episode.
On the Junk poster (Tom Jane's film) it says: "From the directors of Dangerous Cousins". That's the movie George Michael wanted to see with Maeby and where they were kicked out due to being underage.
Michael remembered Tobias's last words, where he said something he considered idiotic, and later said to Lindsay "He said some wonderful things". This is a callback to "Visiting Ours".
Continuity: The scene where Tobias is doing clenching exercises, he is sitting at the right side (his right) of the chest at foot of the bed, but when they cut out as Lindsay comes into the room and cut back to him, he is sitting at the left side of the chest.
When Lucille arrives at the police station to find that they have found Oscar, not George Sr., it is visible that Oscar (a bachelor) is wearing a wedding ring.
When the family leaves the bathroom after walking in on Lindsay, for a split second, we can see someone's reflection in the mirror. This person is wearing a blue shirt with black pants and is sitting down.
Barry Zuckerhorn's secretary, who filed an employment discrimination suit against Barry when he called him a homo in "In God We Trust", was at Tobias's book reading.
The "Visiting Hours" sign in the hospital has the H missing, referring to the episode Visiting Ours.
George Sr: I have the worst f[bleep]ing lawyers".
This was originally spoken in the pilot episode.
Tobias's book reading schedule (seen just before he gives his book reading) is for the following dates: Saturday, Sunday, Here, There, Another Place, Another Time, Everywhere, Monday, Monthly.
The gay French-named bookstore where The Man Inside Me is given a prominent display is named the "Livres Aux Folles" ("Books of a feather").
When Michael first comes in to tell George Michael to pack his bags (before the phone rings), George Michael is drinking a tall glass of soda and eating a sandwich (they're on the Atkins Diet if you don't remember). Michael keeps glancing at the table during the whole conversation.
The "customers who bought this book also bought" section of Amazon's page for Tobias' The Man Inside Me includes Tobias' Families With Low Self-Esteem video, George Sr.'s Caged Wisdom, a Girls With Low Self Esteem video, and The
Low-Carb Gay, Bi, and Transgender Diet, listed as authored by B. Zuckerkorn.
One of the police officers makes reference to having daughters who seem to have run off somewhere. In the next season, the same officers are a couple and hire Maggie to be a surrogate mother so they can finally have children. Their next appearance completely disregards the fact that they already have kids.
When Buster runs through the kids, you can see the football being left behind Buster. But in the next cut, he is kicking it in front of him.
In the "On the next Arrested Development" gag, Lindsay's statement "I want to be... a cage dancer" (and subsequent giggle) is an echo of Tobias's declaration that he wants to be an actor (with the same giggle) in the pilot episode.
When Oscar receives a call just before Lucille visits, a character on Oscar's television can be heard saying "Look! A seagull!", which is a line from the Mr. Banana-Grabber cartoon. Gob gave up the animation rights to Mr. Banana-Grabber in the episode "Charity Drive".
-"Where are the weapons of mass destruction?".
-"You can take away our stylists... but you can't take away our STYLE!".
-"War is SEXIST!".
-"War is RACIST!".
-"Larger free speech zone!".
When Lindsay is protesting, one of the protesters is the same protester from the pilot and the storming the castle episode, namely a homosexual with a boa and a freedom sign.
When Lucille visits Oscar in the supposed lemon grove, buildings and golf carts can be seen over her shoulder.
