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.

Jeremy Renner, aka Hawkeye, was the latest "Avengers" actor on "The Tonight Show," and on Tuesday night he discussed his haircut journey, and sang a hilarious, heartfelt, surprisingly perfect song in honor of his character's lesser-known powers.

You have to see his cute little bowl haircut from the '70s. He has some issues with his mom for that look. He also talked about his band in high school, Hot Ice. Speaking of performances, watch Jeremy as Hawkeye, singing about his super powers to the tune of Ed Sheeran's "Thinking Out Loud." "But listen I've got powers too and they're pretty sweet/Promise I can do so much more than just archery." The whole thing is awesome. And he can really sing! The full lyrics are listed with the YouTube video. "When I go to Chipotle I get free guac" still has us laughing. Michael Keaton was on "Late Show with David Letterman" and shared his Oscar revelation (illness always wins!) and a great tribute to Letterman. The great John Cleese was on "Late Night with Seth Meyers" talking about Monty Python reuniting. He said all the Pythons were scared that people wouldn't laugh at their shows, but he said it was like all your best friends reuniting in heaven. John also talked about the "Dead Parrot" sketch. Linda Cardellini was on Seth's show and talked about the late great "Freaks and Geeks" show. The cast was part of the Thanksgiving Day parade and they got heckled, with people yelling "Who are you?" and flipping them off. Nikolaj Coster-Waldau was on "Conan" talking about "Game of Thrones" spoilers, saying it's sometimes fun to tease fans with fake spoilers. He did one with a duck for HBO Nordic and some people thought they knew exactly what he meant. He shared a new "spoiler" about the dragons (it's good) and talked about his bowel movements. (!) He shared a story from a college trip to Africa, where he went almost two weeks without pooping. When he came home to Denmark it was the most blissful pooping. Conan said there was something rotten in the state of Denmark. Haha. Tim McGraw and Patricia Heaton were both (separately) on Jimmy Kimmel Live, and Tim performed "Overrated" and "Shotgun Rider." Patricia talked about an inappropriate text that her son sent her. Here's Tim talking about how he's played in some rough places, and then Tim discussing his role as a N.A.S.A. engineer in "Tomorrowland." The second movie includes a new clip of "Tomorrowland." 'Jimmy Kimmel Live!': Tim McGraw Has Played Some Rough Places
Anna Faris, Tituss Burgess, and David George Gordon were on "The Late Late Show with James Corden" and for whatever reason they started eating bugs. Those tarantulas ... ugh. Anna Faris said she found her bug soul mate in husband Chris Pratt. She had a dead bug collection when she and Chris first started dating, and it turns out he did too. Anna and Tituss both love "ratchet TV" and talked about that too.
