Yes, Prime Minister1986

Jim Hacker:
Tell me, General, where is the Hot Line?

General Howard:
Which one?

Jim Hacker:
The one to Russia.

Bernard Woolley:
The Red Hot Line, Sir.

General Howard:
That's in Downing Street.

Jim Hacker:
So in an emergency, I can get straight through to the Soviet President?

General Howard:
Theoretically, yes.

Jim Hacker:
Theoretically?

General Howard:
That's what we tell journalists. In fact, we did once get through to the Kremlin, but only to a switchboard operator.

Jim Hacker:
Couldn't the operator put you through?

General Howard:
We never found out. He didn't seem to speak much English.
