This is an I-Heart podcast.

Guaranteed Human.

Hey, and welcome to the Short Stuff.

I'm Josh, and there's Chuck, and Jerry's here for Dave, and we're just hopping along, talking about kangaroos and how they hop.

That's right.

I want to thank our old colleague, Kristen Conger, for writing this article from How Stuff Works back in the day.

And creator of unladylike the podcast, too.

As well as Jennifer Horton wrote another article that I used.

Great too.

And then I think the San Diego Zoo website and Nat Geo all pitched in for this one.

I thought this was a particularly well-researched short stuff.

So I should have known that Jennifer Horton and Kristen Conger had something to do with it.

Yeah.

So we're talking about kangaroos a little bit, mainly going to get to how and why they hop.

But we should start out by talking about the fact that roos are marsupials or pouched mammals because they have a marsupium, which is a little pouch where their little joys develop.

Yeah. We talked, I think, a lot about this in the Naked Mulrat episode, where essentially, like, the marsupial fetus does not develop as long inside the body of the mom as it does inside the pouch.

Essentially, at some point, it's what you would call born, but really it's just crawling out of the birth canal, outside into the world for a second,

and into the pouch. And then the little Joey latches onto a nipple in there. And the nipple

grows three times in size, just like the Grinch's heart. And so the little Joey couldn't

let go of the nipple, even if he or she wanted to, until they develop a little further. It's quite ingenious. Hats off natural selection. That's a great one. Yeah, that's maybe the fact of the podcast for me. That's kind of nutty. Oh, I'm sorry, I took that. I didn't realize that it wasn't. What do I have to always take the fact of the show? I like to, you know.

I mean, I know it's in my contract and not yours, but I'm willing to give every now and then.

That's very generous of you. Thank you.
