Don't get mad, get even. This week on How To Do It: The Guide to Things You Hope You'll Never Need To Know, Sarah Treleaven and Josh Bloch learn how to exact revenge. They speak with author Thane Rosenbaum about how humans are hard-wired for revenge, and hear real-life stories of revenge from petty workplace frustration to an epic, moving story of filial vengeance. Plus, a field trip to The Forgiveness Project, where a group of young people is working to turn the instinct for anger and retaliation into something more positive.

Listen and find out if revenge is, indeed, a dish best served cold.
