Petroleum oil

By the year 3010, petroleum oil is no longer in use, as all of the Earth's reserves ran dry in 2038. However, in a non-canon segment of The Futurama Holiday Spectacular, Bender Bending Rodriguez uses it in Robanukah. He creates a new tradition for the holiday that involves Fembots like Ruth and Esther wrestling in it, while wearing bikinis. When he realizes that they only have enough oil for four and a half weeks, when Robanukah lasts for six and a half, and that there is no more oil in the Earth, he convinces the Planet Express crew to drill deep into the Earth. However, the pressure makes half of the ship cave in, killing all the crew members except for Bender. After staying in the Earth for 500 million years, the dead crew turn into Petroleum Oil. Bender collects an amount and goes back to the surface, and is surprised to find that the oil that was supposed to last for four and a half weeks actually lasted for 500 million years. He proclaims it a miracle.
