Futurama: 10 Most Annoying Little Inconsistencies

10. Why Wasn't Cubert The Professor's Heir Already?

While The Simpsons has its Treehouse of Horror episodes typically once a season, Futurama has the Anthology of Interest. There may have only been two of these so far, but they are among the more popular entries in the entire Futurama back catalogue.

In 'Anthology of Interest Part I', one of the three stories told is about how the Professor named Leela his new heir. This was followed by the Planet Express captain going on a killing spree, taking out the likes of Amy, Bender, Hermes, Zoidberg, and Cubert before it was just her and Fry left.

The whole piece was based around the Professor not previously having an official heir named, but wasn’t this exactly the basis of a different episode earlier in that same season? A Clone of My Own came five episodes prior to 'Anthology of Interest Part I', but was seemingly ignored here.

The Professor created Cubert literally with the specific motive of him being his heir, yet five episodes later he had no one and thus named Leela. Why would this be the case? Cubert was even in this particular Anthology story, so how could his entire reason for being alive have been forgotten about so quickly?
