This is Freakonomics Radio on Marketplace.

Here's the host of Marketplace, Kyra's Doll.

Time now for a little bit of Freakonomics Radio that moment in the broadcast every couple

of weeks where we talk to Steven Dubner, the co-author of the books and the blog of the

same name.

It is the hidden side of everything.

Dubner, how are you, man?

I'm great.

Thanks, Kyra.

I've been thinking about you, actually, lately.

Really?

Yeah, I've been reminiscing.

I was thinking about the very first radio piece that you and I did together back at Yank

Stadium.

Oh, Yank Stadium, yeah.

Let me take you back here, all right?

So here we are, and this is great, and I'm having a good time, but the game doesn't start

for like an hour and a half.

Why are we at Batting Practice?

So you remember that, Kyra?

Yes.
