From this week's episode. The Doctor and a young college student are trapped in a bizarre, imminently life-threatening situation from which there seems to be no exit.
-----
Student: I'm afraid!
Doctor: Don't be.
Student: Why?
Doctor (fiddling with some practical thingum in his hands):
It doesn't help.

THANK YOU, o rascally TV, for this pure moment of Zen...
Be blessed, all--
