If you do, do you get along with them? Yeah, it's not easy. I'm about to visit my niece and nephew.

And I gotta say, for a brother and sister, they get along really well. Maybe I'll get them to

share their secret for always getting along. Come on, let's go find them.

You're tall stupid. Mine's awesome. No, yours is stupid. No, uh, mine's the best. No, mine is.

Mine is. Mine. Mine. Whoa, whoa, whoa. Jacob, Olivia, are you fighting? He's making fun of my

doll. He says it's lame. Yeah. Because it is. No, my doll's pretty. Yours is ugly. Whoa,

whoa, that's not nice. Plus, you're embarrassing me in front of my friends. Sorry, Uncle Jay.

What dolls are we even talking about? My Barbie. Lame. How can she be lame? She has a

Dune Buggy, a surfboard, and a dreamhouse with an elevator.

Yeah, while my GI Joe has a remote control deep with a rocket launcher that hits actual rockets.

Whoa, you could shoot your eye out with that thing. Don't worry. Mom hid the rockets.

Good. Now, let's see if I can solve your problem. Tell him that Barbie's the best.

No, tell her that GI Joe is the best. What if I told you both? You're both right and that they're

both the best. Huh? That's right. But first, we need to understand where Barbie and GI Joe even

came from. Who thought up these kinds of toys? And how have they evolved? It's time for another

with a science in history on. Who smarted? Who smart is it you? Is it me? Is it science or history?

Listen up. Everyone, we're making smarting lots of fun on who smarted.
