Just when we thought Love You, Mean It couldn't get any funnier, this happened: Will Ferrell sat down with Whitney Cummings to discuss his epic mustache, unintentionally being a Packers fan and how his kids are too old for nipples.

Something else the funnyman divulged? The secret to a happy marriage. In this bonus clip—which won't make it onto tonight's show because there's too much hilarious footage—Will tells Whitney how to stay happy when you're married, and the secret is rather surprising. (Hint: It involves some carbs.)

Watch the bonus clip above and make sure to tune in to tonight's Love You, Mean It with Whitney to see the full interview at 10:30/9:30c only on E!
