What's your favorite Doctor Who episode?

My ultimate favourite is 'The Day of the Doctor' - It is epic! Ten and Eleven together! Bad Wolf! John Hurt! Gallifrey saved! The Doctor's quote at the end and all the Doctors lined up on Gallifrey! It's an episode that makes me proud to be a whovian!
Also, I've got to give credit to: Midnight, Blink, The Waters of Mars, Father's Day, The Parting of the Ways, The Girl in the Fireplace, School Reunion, Turn Left, The Eleventh Hour, Vincent and the Doctor, The Impossible Astronaut, The Doctor's Wife, The Angels Take Manhattan, The Snowmen, Deep Breath... There are so many episodes - I could list more that I love but I'd probably take up a whole page! :D

Okay... I think, it's Bad Wolf / The Parting of the Ways. And I love so much: Father's Day, Dalek, Partners in Crime, Midnight, The Stolen Earth / Journey's End, Listen. In general, my favourite episodes are Nine/Rose episodes.
