Hey, Guy Rally! Hello, Mindy! How's it going, buddy? It's going well, thanks.

So I've got a serious question for you. Okay. What kind of dog loves to take baths?

Well, actually, Mindy. Okay, Guy Ross, it's a joke! What kind of dog loves to take a bath?

A shampoo doll! Oh, huh? Okay, moving right along. Well, actually, Mindy, that brings me to

a science story. Who has love stories? What do you have? Well, you know that old saying about

humans and dogs? Oh, yeah. Never eat a dog unless it's in a bun. It was something like never

eat a dog if it can run away from you. I don't know, Guy Ross. I don't know what the saying is.

Actually, the old saying I was thinking about Mindy is dogs are man's best friends.

I'd never heard that one. We call dogs our best friends because, you know, they're loyal and

loving no matter what, even on a bad day. Or a bond. You know, even on a bad day, Mindy,

your dog will still love you. Yeah, and it'll show you that love by slapping all over your face

and eating your shoes. But Mindy, the reason why dogs and humans are such good pals might have

something to do with evolution. Oh, evolution! So like the way we've changed over millions of years.

Exactly. We humans have changed over time. We've had to learn how to cooperate with each other

in order to make sure that we survive. Oh, we knew all about cooperation, Guy Ross.

So you remember that one time I asked you to put your cell phone in the aquarium so that I could

talk to the fish and you didn't want to do it, but you did it anyway because you're a good friend

and also because you fell into it. That was cooperation. Yeah, exactly. And, you know, long,

long before humans had cities or forces or supermarkets or airports or taco trucks. Yeah,

right. Right. Long before we had all of those things, Mindy, we had to find food out in the wild.
