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.

Monday night marked James Corden's debut as the new "Late Late Show" host, replacing Craig Ferguson. Tom Hanks and Mila Kunis were his first guests, and you can see they redesigned the set so they're all just sitting next to each other. Mila went on record to say she loved being pregnant and loves being a mom. Bold stance! James told a story where he thought he and his wife were being followed by paps but the photog was really shooting Ashton and Mila. The three of them talked about their kids, and Tom said he is the new face of "manspreading."

In the second video, James introduced himself and the band, stayed humble and self-deprecating, and paid homage to Craig. He promised to look after the show for him. James' laugh is quite something.

In the third video, Tom and James re-enacted every Tom Hanks movie in just under seven minutes. Classic! He could start rivaling Fallon with these bits. January Jones of "Mad Men" was on "The Tonight Show" and she and Jimmy Fallon played a new game called Pie Golf, along with Bubba Watson. Jimmy and Bubba had to land their shots or January would smash a pie in their faces. Very Betty Draper of her! Jimmy Kimmel is back in L.A. after his week in Austin and he talked to Chelsea Clinton about her time in the White House, her daughter, social media, and her love for action movies. She and Jimmy also did a Serve a Year PSA to get more young people to volunteer a year of their lives to national service. Jesse Tyler Ferguson was on Seth Meyers talking about "Modern Family" and seeing the show's kids grow up. The gorgeous (blonde!) Christina Hendricks was also on "Late Night with Seth Meyers" and talked about the end of "Mad Men." They filmed it several months ago but now that the fans will see it, she knows it's really almost over. She knows how the series ends but she's looking forward to seeing the episodes herself. She is happy with the conclusion of Joan's story too, which is encouraging - especially since she didn't think it would ever be good enough. Ben Stiller was on "Late Show with David Letterman" and talked about teaching his son stripper etiquette. It's funny - his son is learning to read so he reads aloud what he sees, and one time it was when they were passing a strip club, so he read "live nude dancers." So Ben and his son had to have an awkward chat.
Naomi Watts was on "Conan," talking about how her whole family sometimes gets around NYC on bicycles and how her kids help cover her in fake blood for movie scenes. Can you believe she and Liev Schreiber have been together for 10 years now? They are both so lucky. Nick Kroll was also on "Conan," talking about his favorite "Kroll Show" characters and his one celebrity impression.
