During his Late Show monologue Wednesday night, Stephen Colbert went in on “former speaker and talking bag of laundry” Newt Gingrich for his contentious and ultimately embarrassing interview with Fox News’ Megyn Kelly the night before.

When Kelly brought up the accusations of sexual assault against Donald Trump, Gingrich accused her of being more “fascinated with sex” than she is about public policy. First of all, Colbert told Gingrich, “Everybody is more fascinated with sex than public policy.” If you’re not, he added, “there’s a pill for that now.”

But that wasn’t Colbert’s main point. Instead, he stressed that Kelly wasn’t talking about “fun time bedroom whoopee-making, she’s talking about assault.”

“Wait, unless Newt doesn’t know the difference,” Colbert continued. “Maybe no one gave him the talk.” Turning to a different camera, he spoke directly to the Trump surrogate. “Newt, sweetheart, you’re growing up so fast,” he said. “In fact, you’re 73. Your body’s changing. You’ve probably noticed some strange new hair growing on your earlobes. It’s perfectly natural.” Colbert told Gingrich that he may finally be old enough to learn about “the birds and the bees and the consent.”

“You see, when a man has special feelings for a woman and he wants to give her a special hug, he asks her a special question: You up?” the host said. “But grabbing a lady because you’re a TV star is not sex, it’s assault. And fun fact, assault is a matter a public policy, because it’s illegal. Even if you use Tic Tacs.”
