We're launching Podlandia AO Rewatch, our brand new podcast where we revisit every episode of Portlandia together, breaking down sketches, going deep on our iconic characters, and pulling back the curtain on how it all got made.
And we'll also be joined by the people who helped bring it all to life. Guest stars, collaborators, and friends, including director Jonathan Kreisel, the mayor himself, Kyle MacLachlan, legendary musician Amy Mann, and many more.
Kyle is going for it here. You fully improvised, not just words, but a song, a melody.
Well, I thought you were all going to write a song.

Hey guys, it's me, Josh, and for this week's Select, I've chosen our August 2023 episode on plant migration. This one makes me a brainy boy, what with its earth science and something that goes on under our noses without us really realizing that it's happening. And we figure out that there's a lot to learn about plants on the move, which makes it even sweeter. I hope you love this one as much as I do.
Welcome to Stuff You Should Know, a production of iHeartRadio.
Hey, and welcome to the podcast. I'm Josh, and there's Chuck, and Jerry's here too. And this is Stuff You Should Know, the We're All Melting edition.
Yeah, I'm just a migrating fern. Oh, that's a good one to be. Blowing through the forest looking for a new home. Sure. I'm a spore.
What happens when you get there, spore?
Well, I'll probably grow into a beautiful new fern because ferns are pretty hardy.
That's awesome. And I'll bet you'll contribute to society in all sorts of beneficial ways that ferns that were already there couldn't necessarily do.
I hope so. There is fern stuff in here, and I have a wonderful fern scene at my camp on the other side of the feeder creek that goes into the main creek. I even have a sign that says fern forest, and it's a forest of ferns. It's quite lovely.
God knows where they're from because those things can travel quite a bit, as we'll see.
Yeah, they could be from Alabama. Easily.
I'm not kidding. Easily, man. I've got a stat that's going to blow your mind in a second.
Oh, boy.
Actually, I'll just bust it out now. You ready? Yeah.
How far can a fern travel?
A fern can travel, the Tasmanian tree fern in particular, can send its spores 500 to 800 kilometers. It's 300 to 500 miles from the mother plant. And get this, a single frond, a frond, produces more than 750 million of those spores. So you can understand that ferns, I mean, you find ferns everywhere.
