Duck Dynasty stars Willie and Korie Robertson are opening up about their parenting style.

The couple has raised five children together over the past two decades, and are now channeling their lessons learned into Korie's new book, Strong and Kind.

"The plethora of parenting books can lead one to think that good parenting is nearly impossible," Korie says. "But being a good parent is really pretty simple. I'm not saying it's easy, but I am saying it's not as difficult as some of today's parenting experts would lead you to believe. You can be confident of this: God has given you the ability to raise the children He has given you, and He has provided you with the best parenting book on the market, the Bible."

The book aims to empower parents with the tools necessary to build strong character in their children through – you guessed it -- strength and kindness.

In the video above, Korie and Willie challenge each other to identify which parent is stronger or kinder in various situations -- hilariously revealing the one subject that makes dad Willie a total pushover: money.

"You're the one who gives in to everything!" Korie teases her husband. "I look like the bad guy, 'cause I say no to something, they come in there and ask daddy, and he's flipping out the bills."

Willie can’t deny it, cracking a big smile as he explains his reasoning.

"If it's a great sales pitch on why they need the money," he says, "it's like Shark Tank in there."
