3. Futurama
Unsurprisingly, Matt Groening has carried the Doctor Who references across to his other acclaimed animated series, Futurama, and once again it's the Fourth Doctor who's been getting most of the action. And rightly so, of course. To date, Tom Baker's Time Lord has appeared in episodes including Möbius Dick and All the Presidents' Heads. In the latter, screencapped above, he was seen stepping off a doubledecker bus and into his iconic TARDIS as an added reference to the events of the 2009 Doctor Who special Planet of the Dead. What's more, the show's creator has revealed that one of Futurama's main characters, Leela, was in fact named after the Fourth Doctor's devoted companion, although that's seemingly where the similarities end, especially seeing as this Leela has a purple hair and... well, one eye.
