Starting from this episode, in the opening title the old woman is no longer walking a parrot, but a chicken.
When Mabel is in the boxing ring, you can see her shoulders and back clearly. The Whale tattoo from season 1 is missing.
When Oliver is wearing his night clothes, he says that he looks like Nick Nolte the day after Mardi Gras. Martin Short and Nick Nolte were the two leads in Three Fugitives.
Oliver jokingly makes a comment saying, "I'm so Greek, I could be Jennifer Aniston's stand-in." Martin Short (Oliver Putnam) has worked with Jennifer Aniston in the TV show, The Morning Show (2019), playing Dick Lundy and Alex Levy respectively.
