Crime fiction references
The mansion of Fat Tony also strongly resembles that of Tony Montana from the movie Scarface.
Fat Tony's son, Michael, is named in honor of Michael Corleone, son of Don Vito Corleone, in Mario Puzo's The Godfather Trilogy. His hairstyle is also extremely similar to Al Pacino's coiffure around the time of the picture.
At the end of the episode Michael says to Lisa: "Don't ever ask me about my business", a quotation from The Godfather. The room where this takes place is very similar to the location in the original movie.
The final portion of the episode is a reference to the final scene of The Godfather, Lisa plays Diane Keaton, and Michael (whose character resembles a young version of Michael Corleone) plays Al Pacino. The Godfather theme is also heard.
Homer claims Shark Tale to be the best gangster movie ever.
Fat Tony asks "Who wants to sleep with the fishes?" Because I brought this Finding Nemo bedspread!" "Sleeping with the fishes" is a gang language quote for dumping a dead body into the river. This is also referenced in '''The Simpsons Movie''' where Fat Tony tries to dump his "yard trimmings" into the Springfield river and A Fish Called Selma, where he used the phrase and got misinterpreted by his fellow mobsters as saying that Troy McClure had died (when he in fact was meaning that the latter had literally "slept with the fishes" at the Aquarium, referring to having his sexual relations with fish).
Something similar to the yard trimmings example also happened in Mom and Pop Art, where Louie claimed they were "donating" a "beanie baby" (which was actually a rolled up rug with an implied dead body inside) to the Toys and Tots bin, although in that case it was not at a body of water.
The episode title is a reference to the film The Cook, the Thief, His Wife, and Her Lover, which also involves a crime boss and food.
When Fat Tony arrives for the carpool, he says "We are going for a ride!.... By which I mean the carpool." Much of Fat Tony's quotes is related to gang language.

After first finding out Fat Tony is Michael's dad, Nelson also comments "Columbus Day is better than Christmas". This is based on the real-life controversy surrounding the Columbus Day holiday; critics citing Christopher Columbus' slaughtering of Native Americans due to comments made in Howard Zinn's history book A People's History of the United States, while supporters, many of whom are of Italian ancestry, view him as an Italian-American hero. The controversy is addressed in The Sopranos episode "Christopher" (from the show's fourth season).

Bart says that he passes the yellow lights (traffic lights) and Marge thought it was a joke. Although the yellow lights of the traffic lights can be pass without any problem.
When Fat Tony gives Michael the math notebook, the back window of Marge's car is withdrawn. This would be impossible in real life, as the back window cannot be removed.

In slow motion, when Homer was eating the poisonous meatballs, the sticks go through the plate.
When Bart and the mob walk into the Krusty Burger's backroom Krusty's nose is white, but after it cuts back to Bart and the mob the nose is red, even though it is possible that he put on the clown nose off camera.
This is the second time Otto has gotten suspended from driving the school bus, the first time was The Otto Show.
Similarly, this was the second time a reprimand happened with the bus/bus driver that forced the parents to carpool their kids, the first was in Homerpalooza after Otto drove the bus into the pressing engagement after steering off the street in an attempt to avoid running down Jasper Beardley at the last second after sleeping at the wheel.
