Welcome to Stuff You Should Know, a production of IHeart Radio.

Hey, and welcome into the podcast. I'm Josh, and there's Chuck and Jerry's here too, and this is the podcast, as just mentioned.

We call it Stuff You Should Know. And by the way, we should say to any new listeners,

we're not saying you should already know this stuff. So don't be hostile toward us about that.

We're saying we think you should know this because it's so interesting. We want to tell you

about it. Yeah, we could have changed the name of the show to things that you might find interesting,

but then again, you might not as well.

But that doesn't have a ring.

Yeah.

There's no implied dummy in the title of our podcast.

Okay.

No, no, no.

We're the dummies.

So I'll tell you somebody who wasn't a dummy as far as it comes to being a world-class liar.

Maybe England's greatest liar ever.

It was a spy from the World War II beginning early Cold War era named Harold Kim Filby.

And if that name rings a bell, we'll just sit back and enjoy this episode on a British

spy. If you don't know who Kim Filby is, sit back and enjoy this episode on a British spy.

Your voice is going up like you were going to say something else. Is that it? I just wanted

to replicate it perfectly. So big thanks to Dave who

helped us with this, but Dave also wanted us to shout out, and we want to shout out a book by

Ben McIntyre, A Spy Among Friends, Colin Kim Philby, and The Great Betrayal. And also, a mini-series
