From Tardis Wiki, the free Doctor Who reference

We don't cover The Simpsons simply because the Fourth Doctor has appeared several times. Instead, we consider that a cultural references to the Doctor Who universe.
The thing is, Magrs is having his characters travel between series. They're not references. Panda being in a Brenda and Effie book is more than just a reference here.
