Dr who fourth doctor quotes The Creature From the Pit

The Doctor: I suppose you could say the yoke's on him if you were the sort of person who said that sort of thing which fortunately I'm not.

The Doctor: Stupid expression, 'stands to reason.' Why isn't it 'lie down to reason?' Much easier to reason lying down.

The Doctor: Well, to be fair I had a couple of gadgets he probably didn't, such as a teaspoon and an open mind.

Romana II: So Erato came here to offer you metal in exchange for chlorophyll. Of course!

The Doctor: Right. But who was the first person he met?

Organon: The person who held the monopoly of metal.

The Doctor: Right! And did she put the welfare of her struggling people above her own petty power? No... she tipped the ambassador into a pit and threw astrologers at him!
