Yes, Prime Minister1986

Sir Humphrey Appleby:
[Sir Humphrey has just proven that, despite what the Prime Minister says, he still knows Latin] Si tacuisses, philosophus mansisses.

James Hacker:
What does that mean?

Sir Humphrey Appleby:
If you'd kept your mouth shut, we might have thought you were clever.

James Hacker:
I beg your pardon?

Sir Humphrey Appleby:
Oh, not you, Prime Minister. No, that's the translation.

Bernard Woolley:
No one would ever have thought Sir Humphrey was saying that about you.

Sir Humphrey Appleby:
Go away, Bernard, please.
