Doctor Who

Doctor Who is a long-running British sci-fi show. Matt Groening claims to be a fan of Doctor Who. In the Doctor Who episdoe Planet of the Ood, one of the Ood's programming functions is 'classic comedy', the OO worker says "Ood, you've dropped something", and the Ood replies with "D'oh!" In Treehouse of Horror X, Comic Book Guy, aka The Collector, has Tom Baker's incarnation of The Doctor concealed in plastic, along with many other geek-show characters. He introduces The Doctor as Doctor Who (the character's common nickname) to Bart Simpson, aka Stretch Dude and Lisa Simpson, aka Clobber Girl.

The Doctor also makes an appearance as one of the representatives of T.V. in Sideshow Bob's Last Gleaming.
