The Lavender Hill Mob1951

Henry Holland:
A minute later, the guard will appear around this corner, and you, Pendlebury, will detain him for at least half a minute. Ask him for a light, ask him the way, ask him anything, but keep him there, we must have those thirty seconds.

Pendlebury:
Edgar.

Henry Holland:
I beg your pardon?

Pendlebury:
Isn't one supposed to say that when one's being briefed? On my rare visits to the cinema...

Henry Holland:
The word is "roger."

Pendlebury:
Oh, roger. How silly of me.
