Arrested Development

The images of the Bluths at the beginning of Scandalmakers were from the opening credits. The arrow pointing to Michael can even be seen on his picture.

The narrator makes mention of how the narration for Scandalmakers is "real shoddy", "just plain crap", and that his inattention to detail "perplexed the audience, due to the unfocused nature of the narrator's explanation". However, Tobias is seen sitting inside the fireplace on three occasions in the episode, without any precedent or apparent reason, leading the viewer to assume the narrator is guilty of some "shoddy narration" of his own.

It's revealed that Michael was born 12 years after Sugarfoot had gone off the air (1961). If we consider that the present day for the series is the same as the airdate of the episode, Michael should be 32. Since George-Michael is at least 15, that means Michael had him when he was 17.

A movie poster for the Tom Jane (who appeared in the episode "The One Where They Build A House") movie Junk can be seen in Maeby's office.

When Lindsay is confronting Phillip Litt, we see the Marina Hornblower, the yacht where George Sr. had his retirement party along with a sign that says "Catalina Shuttle", which the Bluth Company employees mistakenly took in the season 1 episode "Staff Infection".

When Kitty flashes her breasts just after Michael has just acquired a deal with Cal Cullen, the cameraman (or someone) clearly uses their own hand to cover the camera's lens to avoid the shot of her bare breasts.

When Maeby and George Michael are at the banana stand, two familiar logos can be seen. On one T-shirt is a Cloud Mir logo and on another is a Tau Omega Alpha. They were displayed on a sign when Michael was talking to George Michael on the yacht in the season 1 episode "Missing Kitty".

At the end of the episode, Lucille mentions while choking Michael that there were 250 cc of George, Sr's semen in the cooler. This is reminiscent of the episode "Top Banana" when George Sr. yells at Michael telling him that there was $250,000 lining the walls of the banana stand that Michael burned down.

The cooler now contains evidence to exonerate George, Sr. However, in first season's "Missing Kitty," George Sr. made a call presumably to Gob to get rid of the evidence contained in the cooler which led to the sinking of the yacht.

Even if we assume that Lucille hid George Sr.'s semen in the banana stand after it was burned down and rebuilt, it doesn't change the fact that such a specimen must be stored in liquid nitrogen (not in an ordinary freezer).
