Yes, Minister, Series One (1986)

Godfrey:
Will you be wearing those glasses?

Hacker:
Oh, well, what do you think?

Godfrey:
Well, it's up to you, obviously. With them on, you look authoritative and commanding; with them off, you look honest and open. Which do you want?

Hacker:
Well, really, I want to look authoritative and honest.

Godfrey:
It's one or the other, really.

Hacker:
What about starting with them off, and then just putting them on when I talk?

Godfrey:
That just looks indecisive.

Hacker:
I see.

Bernard:
What about a monocle?
