Trivia: When Lrr and Nd-Nd are dining at the park, trying to get in "the mood", Lrr gets very agitated at his wife. He jumps up and screams to her "One of these days, Nd-Nd, bang. Zoom. Straight to the third moon of Omicron Persei 8." This is a spin-off from the 50s TV show The Honeymooners, in which one of the characters says almost the exact same thing to his wife, Alice.
Trivia: At the beginning of the episode, when Fry walks into the room wearing an orange space suit, you can see that Amy is busy reading a book (so busy she doesn't mind the odd liquid inside Zoidberg's bathtub being splattered all over her). The book's title is "Martians are from Mars, Venutians are from Venus."
Trivia: This season was compiled of previously unaired episodes. There were 4 production seasons, but not all of the episodes had been aired due to various reasons. These include Fox thinking some were inappropriate (including "Tale of Two Santas") and schedules being limited.Dan Moat

Trivia: When the head of Al Gore meets everyone in the big dome to discuss the problem with Global Warming, he comments that, according to his books, "Earth in a Balance" and "Harry Potter and the Balance of Earth", that everyone needed to protect the Earth from global warming and "black wizards." Then it cuts to Tim the Wizard, from Monty Python and the Holy Grail, sitting in the audience, rolling his eyes and saying "Sure, blame the wizards..." Also, whenever Gore shows that the prize for whoever can solve the global warming problem is a bag of moon sapphires, Tim says "Sapphires? I can use this to get through the gate. hahahaha..."
