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.

Seth Meyers had the cast of "Parks and Recreation" on his show Tuesday night for their big final goodbye. Amy Poehler, Chris Pratt, Aziz Ansari, Nick Offerman, Aubrey Plaza, Adam Scott, Retta, Jim O'Heir and Mike Schur discussed filming the finale, and revealed their own pitches for how they wanted the show to end. Since it's also the one-year anniversary of Seth's show, they sang an anniversary song for him, but they didn't rehearse it, so it didn't go too well. What did go very well was their "Bye, Bye Li'l Sebastian" song on the way out -- complete with Jim (Gerry) and Aubrey (April) making out, to the surprise of everyone around them. Yes, that is what you are seeing. Love Retta's reaction: "I can't look at it. I can't look." Tears! Josh Duhamel and Gabrielle Union (gorgeous!) were both on "The Tonight Show" and played "Random Object Shootout" with Jimmy Fallon. It's a huge waste of food, and someone will have to clean it up, but it's still fun. Josh is the ringer! Josh talked to Jimmy about his son, and the adventures in potty training. Bella Thorne was on "Jimmy Kimmel Live," talking about the Disney Channel, Woody Harrelson, and when Christian Bale (her favorite actor) recognized her from "Shake It Up." She also talked about food; she's Cuban and loves spicy food. She ate an onion on the air. Will Forte was also on "Jimmy Kimmel Live," talking about the sweet beard he grew for his new show, and his love for "The Bachelor." Will cannot explain his love for the show, but he spent yesterday trying to catch up on stuff earlier this season. Jimmy brought out Chris Soules, who is apparently just always hanging out on the JKL set. Chris brought Will a rose. Matthew Broderick was on "Late Show with David Letterman" and they had the sex talk. Dave asked if Matthew has had "the talk" with his son, and how he would approach that. Victoria Justice was on "Conan" and they showed when Conan and Victoria were at the White House, singing a Christmas song alongside the Obamas, Justin Bieber, Jennifer Hudson, the Band Perry, and Cee-Lo.
