Bender's Decapodian tailor says that his business has been in his family for 7 generations, and that his father only died yesterday- impossible as Decapodians die after mating. Later in the episode, in the background is a newspaper clipping called "The Stickler's Gazette" with an article headline "Tailor's Adoptive Father Dies of Clam Poisoning", clarifying the detail.
The ambulances taking away injured participants of the running of the buggalos have "Soylent Ambulunch" printed on the side. A joke that refers to the sci-fi dystopian film Soylent Green (1973), which is set in a future where the Earth is overpopulated and all natural food sources are gone. Humanity's only source of food comes from Soylent Industries, a company that produces a food wafer called Soylent green, made from plankton in the oceans...or so they claim. The film's main character Detective Thorn, played by Charlton Heston, discovers that the Earth's oceans are too polluted to produce even plankton, leading him down a dark trail that results in him discovering that Soylent green is really made from the processed remains of human bodies. One of the main sources of human bodies are hospitals, where people with anything more than a minor injury are euthanized and sent off to be processed into food, hence the "ambulunch" joke.
The names of the food carts are puns made with letters from the Greek alphabet. The first one is Chu-rho, or churro (Mexican fried dough). The second is Pi-ella, or paella, a Spanish dish often made with rice, olive oil, rabbit, chicken, saffron, tomato, flat green beans, lima beans, salt and water. The final one is Empa-theta or empanada, a Spanish pastry consisting of baked or fried dough stuffed with meat, cheese, tomato, corn, or other ingredients.
