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.

"Game of Thrones" star Maisie Williams (Arya Stark) was on "Jimmy Kimmel Live" Tuesday night, and one of her videos included a clip from Season 5, which starts in just a couple of weeks on HBO. Maisie started playing Arya when she was 12, which is too young to watch the show, but she watched it with her whole family. They had to get her gran drunk when the boob scenes came on! She trained herself to sword-fight left-handed, since that's how Arya was written and that's what the fans expected. She admitted she hasn't read the GoT books ("A Song of Ice and Fire"), though. The second video shares the GoT clip with Arya in Braavos. Kevin Hart was on "Conan" and shared his disastrous "SNL" audition. He was rejected from the show after doing an impression of somebody nobody knew; it lasted about two seconds, and he acted like it was awesome. Kevin also talked about working with Will Ferrell, who is in the top two of the people he's ever worked with. Will is a great guy - "cheap as hell, though" and has never spent a penny. He's still using the first BlackBerry they ever made, it's taped up and looks like a dog ate it. Will is also one of the worst dressers he's ever met. Poor Will! Kevin loves to spend money on clothes but gets offended if people don't notice that his clothes are expensive. Haha. Elizabeth Banks - she's hilarious - was on "The Tonight Show" and arranged a marriage between her sons and Jimmy Fallon's daughters. She also talked about FaceTiming with her kids. Jimmy also shared "Freestylin' with The Roots: Spring Edition." Ben Stiller was on "Late Night with Seth Meyers" to talk about his new movie "While We're Young." One of the Beastie Boys is in the movie and Ben performed live with the Beastie Boys a few years ago. It was the most nervous he's ever been. He's a huge fan. Seth quizzed Ben on Beastie Boys lyrics. Ben also talked about the long-awaited sequel to "Zoolander" and taking tennis lessons in Rome. Elisha Cuthbert was on "Late Night" and shared her craziest "24" fan story - about a pregnant fan who pushed her first birth back so she could watch the show. Bill O'Reilly was on David Letterman's "Late Show" and talked about Brian Williams and accusations of false claims. He boiled it down to America's beloved sport, "Let's Destroy the Famous Person." He thinks Brian will come back. What Bill does is very different from what Brian does - editorial vs. hard news - but Dave said trust is at the heart of both viewpoints. Bill also discussed Ted Cruz and Hillary Clinton.
