Professor, what exactly is a cold war?

Not kidding.

These kids today don't know anything about the Cold War. I mean nothing. I have to start from scratch, the U.S. the U.S.S.R., NATO, the Warsaw Pact, nuclear war, etc. etc...

So I like to show them this:

Walk up to any Gen X'r and shout, 'Turn your key!' and they'll know what your talking about.

These kids had never seen anything like this before and had no idea what they were looking at.

Remarkable.

And thank you President Reagan, thank you Prime Minister Thatcher.
