Professor Richard Lazarus: I find that nothing's ever exactly like you expect. There's always something to surprise you. Between the idea and the reality, between the motion and the act...
The Doctor: Falls the shadow.
Professor Richard Lazarus: So the mysterious Doctor knows his T.S. Eliot. I'm impressed
The Doctor: Wouldn't have thought you'd have time for poetry, Lazarus, what with you being so busy defying the laws of nature and everything.
~~ Dr. Who, "The Lazarus Experiment" (2007)
