Futurama's executive producer David X. Cohen stated in the audio commentary that the title refers to the phrase for sexual intercourse: "the beast with two backs," popularised by William Shakespeare. Incidentally, this phrase was also referred to in the episode "Spanish Fry" where it was the name of a sex store: "The Beast With Two Bucks."
