Yes, Minister, Series One (1986)

Sir Humphrey:
If you walked into a nuclear missile showroom, you would buy Trident. It's lovely, it's elegant, it's beautiful – it's quite simply the best, and Britain should have the best. In the world of the nuclear missile, it is the Savile Row suit, the Rolls-Royce Corniche, the Château Lafite 1945. It is the nuclear missile Harrods would sell you. What more can I say?

Hacker:
Only that it costs fifteen billion pounds and we don't need it.

Sir Humphrey:
Well, you could say that about anything at Harrods!
