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.

"Birdman" star Michael Keaton was on "The Tonight Show" Monday night, and Jimmy Fallon said he wanted to see how good the Oscar nominee could be. So Michael and Jimmy re-enacted scenes from "Birdman" but not the real movie - a version written by school-children. The kids were just asked to write scenes for a movie called "Birdman." So watch them do some Kid Theater. Telling you, some of these "Birdman" scripts are gold. Keaton crushes it. Amazing. Jimmy Kimmel had another unmissable round of Mean Tweets, this time in a Music Edition read off by Josh Groban, Drake, Lady Gaga, Sam Smith, Jessie J, Blake Shelton, Haim, Wiz Khalifa, Ed Sheeran, Iggy Azalea, Pitbull, Sia, Childish Gambino, Britney Spears, Ariana Grande, Jason Aldean, 5 Seconds Of Summer, Katy Perry and Psy. Some of the tweets are genuinely mean (and gross!), but others are just laugh-out-loud funny. Rob Gronkowski was also on "Jimmy Kimmel Live" and he read aloud from a fan's work of erotic fiction called "A Gronking to Remember." Apparently this is just Book 1 from this fan's series. His mom was in the audience hearing all of this. Hilarious! Eva Longoria was also on JKL and she explained her Super Bowl injury from her party. She was so worked up by the final play she fell on her friend and cut herself. Bob Costas was on "Conan," so of course he talked about both DeflateGate and the Super Bowl's final play. Bob joins the ranks of those who believe if the Seahawks had handed the ball to Marshawn Lynch, they'd be the Super Bowl champs right now. But Bob gave props to Malcolm Butler. And we're all sick of the deflated football talk, but Bob said DeflateGate was no big deal and mostly about the modern 24/7 news cycle.

Eddie Redmayne was also on "Conan" and talked about his killer abs in "Jupiter Ascending." He plays a vain space tycoon so he worked out and got fit and it's only blink-and-miss in the film. So Conan got Eddie a gift -- a huge portrait of his character with the abs. They also discussed Eddie's freckles, which have helped him get roles, and it was noted that Eddie is actually a dead ringer for Jennifer Garner Affleck. There's video evidence from one of his early roles!

John Oliver was on "Late Night with Seth Meyers" - and he's such a good watch. Always. He and Seth discussed the Super Bowl, Katy Perry's halftime show, and how much it hurts when your sports team loses. He really lost it when England lost to Germany during the World Cup. He's a Liverpool fan and he met the team, but it didn't go well. He saw them in the locker room and the entire team came out naked - "waving a handless hello" - and it changed his relationship with them. Ha! John obviously talked about "Last Week Tonight" and its new season. "Jungle" Jack Hanna was on "Late Show" with David Letterman and Dave got to hang out with an adorable "bush baby." The cutie sat on Dave's new hat and started jumping all over him. Apparently bush babies pee on themselves to wash themselves? They also brought a venomous cobra out. Poor guy didn't want to be there, and Dave wasn't very welcoming. Dave also addressed the big Super Bowl shocker and shared the "Top 10 Pete Carroll Excuses": Sean Hayes guest-hosted the "Late Late Show" and guest Marion Cotillard talked about the first guy she kissed on screen. Apparently it was bad. Really bad.
