Pts! Hey, Smarty Pants! Care to join me on a picnic? I packed a blanket to sit on, sandwiches to eat,

and I downloaded some Who's Smarted episodes to listen to. We're all set.

I just need to find a good place to sit and... Whoa! Is that? Hey, hey, Smarty Pants,

can you think of a plant you wouldn't want to sit on or near?

It's got three pointy leaves that look glossy or even shiny on top.

Did you say, poison ivy? That's right. I almost sat in poison ivy.

Yikes, there's poison ivy everywhere. Come on, Smarty P pants. Time to pack up and get away from here.

Hey, why doesn't anyone ever want me at their picnic?

Or camping trip, or hike in the woods, or pretty much anywhere near them?

Sure, I'm famous for giving humans an itchy rash, but I have pretty white flowers and sometimes berries.

Uh, no offense, poison ivy, but the answer's pretty obvious. I'm getting itchy just thinking about you.

But what exactly is poison ivy? Where does it grow? And why are humans so allergic to it?

It's time for another whiff of science on...

Who smarted?

Who's smarted?

Who's smart?

Is it you?

Is it me?

Is it science or history? Listen up. Everyone, we make smarting lots of fun on who's smarted.

Hey guys, trusty here with a great idea for a gift that's always on time and lasts a lifetime.

I'm talking about Masterclass. You know,

I use the masterclass platform myself, and you should too. It is incredible being able to learn
