There's a sort of joking, Continuity Nod version in the Big Finish Doctor Who story Caerdroia. The Doctor, dealing with an Obstructive Bureaucrat, says that he's going to go take a couple of aspirin. It was once stated that aspirin is poison to Time Lords. Without knowing that, it sounds as though he's merely, and quite reasonably, complaining of a headache, as he's just been asked to refer his question of whether anyone in the building can help him to the Rhetorical or Genuine Questions Office, but it's actually more akin to an exasperated finger-gun-to-the-head gesture.
