The LJ Writer's Block Question Doctor Who Version

Today's writer's block question gave me an idea. Is there a specific episode of Doctor Who that you play to cheer you up when you are feeling down?

Also, is there another show that you can pop in and cheer up?

Mine would be...Fear Her or The Doctor Dances.

And my other shows would be pretty much any Psyche episode but probably the treasure hunting one most of all. And the Cow Creamer episode of Jeeves & Wooster.
