Stewie tosses his Lifetime Achievement Award into the "Hollow Accomplishments Bin." Amongst others, some of the trophies/awards found in the bin are the NHL's Stanley Cup, the NFL's Lombardi (Super Bowl) Trophy, and an Emmy Award. The Emmy is particularly self-deprecating as, through the date this episode aired, "Family Guy" has won 9 Emmys.
The scene where Peter vapes and puts in his earbuds in the room with Stewie and Chris is a parody of The Godfather Part II (1974).
Peter's comment that a number of guest stars on the show passed away shortly after they appeared in an episode is eerily factual. The vast majority passed away due to their advanced age from natural causes.
When Stewie and Herbert get 'tangled' at the end, among the masks on the wall is one of the characters from Jeff & Some Aliens (2017).
