We had Steven Levitt on earlier this week. The Freakonomics of parenting, if you will.

Steven Levitt: When I was a kid, my parents bribed me. It was just a mainstay of my household, that if I did well in school, they'd give me $50 maybe for every day.

Ryssdal: No, get out of here! Fifty bucks?

I wasn't the only one amazed. Here's a bit of how you responded on our Twitter and Facebook feeds. Listen to the audio above.

You know how to reach us. Or bribe us. Twitter is @MarketplaceAPM. You can get me at @kairyssdal.
