So before last night, Louis CK had not been on David Letterman in over 15 years. I know, right? Don't the people who book that show have a list titled "The Funniest" that he sits firmly atop? That is just ridiculous.
Anyway, last night he made his glorious return. And oh boy was it glorious, specifically his plan for population control, which may or may not include death by lions.
