Weekend at Burnsie's/References

Cultural

 * Some elements of the episode, as well as its title, parody "Weekend at Bernie’s".
 * When the family first finds out Homer is using marijuana, he is singing “Smoke on the Water” by Deep Purple.
 * The music used while Homer is getting stoned on his first joint is "Incense and Peppermints" by Strawberry Alarm Clock.
 * “Wear Your Love Like Heaven” by Donovan plays in the montage of a stoned Homer getting ready for work.
 * Homer’s car during his hallucination as he’s getting ready for work looks like Benny the Cab from Who Framed Roger Rabbit.
 * When Marge is making the scarecrow for her vegetable patch, pop-ups appear on the screen in the style of VH1’s Pop-Up Video.
 * The song Phish is singing is “Run Like an Antelope.” Later, Phish plays the opening limb of the Simpsons theme song, something Phish actually did in their real-life concerts.
 * When Homer smokes pot, he says that it (marijuana) can "make anything funny. Even that show that follows Friends." This is possibly a reference to Frasier, which did follow Friends at the time of this episodes original air-date but is more likely a reference to the numerous -- and usually short-lived -- series scheduled after Friends for many years.
 * When Homer is stoned and talks to Ned Flanders he cites his own example of the Omnipotence paradox: Could Jesus microwave a burrito so hot that he himself could not eat it?"

Previous episodes

 * Seth and Munchie, the hippies from "D'oh-in in the Wind", are in the crowd in the rally for the legalization of medical marijuana.
 * Otto remembers his wedding to Becky in "It's A Mad, Mad, Mad, Mad Marge" after seeing his ring.
 * When Marge takes out some clothes from a box, captions show up when Marge lays them in a shape of a body. These include Lisa's jersey from "Lisa on Ice", Bart's jockey pants from "Saddlesore Galactica", the Jack-o-Lantern from Treehouse of Horror Treehouse of Horror III", IX and XII, and Grampa's fez hat from "Who Shot Grampa's Hat" (This isn't an actual episode title, but the name is similar to "Who Shot Mr. Burns").

Trivia

 * This is one of the many episodes where a Simpson uses drugs. Bart used Focusyn in "Brother's Little Helper", Homer later uses Nappen in "Crook and Ladder", Marge uses steroids in "Strong Arms of the Ma", and Lisa takes Ignorital in "The Good, the Sad, and the Drugly".
 * This is the first episode revealing fully on screen that Otto Mann is a stoner, although we do not actually see him smoking pot until later episodes.
