If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

Here's Stephen Colbert contemplating the mysteries of the universe alongside "Late Show" segment called "Big Questions with Even Bigger Stars." It's like a hilarious midnight picnic with Forrest Gump. The audience cheered for Tom for so long it kinda cut the segment short, but they still spent a lot of time asking deep questions and giving silly answers. For example, they tackled big Qs like "Why do bad things happen to good people?" and "What would you do with a time machine"? It's great. A Hitler-killing baby is involved. Stephen Colbert + John Oliver = Where's Jon Stewart? 'Cause he would complete the trifecta. John got bleeped, saying he doesn't give a toot about Donald Trump right now. But he can't vote anyway, so... After his appearance, John Oliver left a funny video guest book message for Stephen Colbert, offering some tips on the show. "Late Show" guests Bill Withers and Ed Sheeran sat side-by-side and shared something in common: they both had stutters. The best part came after Ed listed all of his medical issues growing up: "The reason I became a musician is God looked down and said 'You probably need some help getting laid.'" The audience cheered. Bill's response: "That's what you call going from ginger to a ginger snap." Ken Jeong of "Dr. Ken" was on "Jimmy Kimmel Live," talking about being a doctor who became an actor, and he did his Korean Johnny Carson impression: Seth Meyers got semi-serious over on "Late Night," taking a closer look at Planned Parenthood and the recent Republican congressional attacks. Good work, man. This is what Seth does best, to be honest. He's in his element when he's mostly "The Daily Show." Over on the "Late Late Show with James Corden," Patricia Arquette, Matt Walsh, Jeremy Irvine discussed sex scene experiences. Which sock do you pick? Quite a dilemma. If you're curious about how "The Big Bang Theory" star Kunal Nayyar lost his virginity, he wrote about it in his book and told the story on "Conan." He was 19, it was anticlimactic and, the next morning, he called the girl the wrong name: On "The Tonight Show," Bravo honcho Andy Cohen offered a guide to Twitter. "We are all just one tweet away from getting fired. Think before you tweet." He also recently insulted Tori Spelling after she was burned, and then accidentally insulted her again when they e-mailed each other. Think before you e-mail too.
Last but not least, here's the beautiful Julianna Margulies drowning in sexual innuendo (grease of the cock?!) when explaining a magazine shoot in the south of France. She's all wet!
