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.

On Tuesday night, Jimmy Fallon welcomed back his panel of adorable puppies to predict the NCAA Championship from among the Final Four. Who will be the national champs - Kentucky, Wisconsin, Michigan State or Duke? Cute puppies crawling over each other in their cutesness = win. Spoiler alert: They must've put something nasty in the Duke bowl 'cause no one went for it. No one. Ethan Hawke and Jimmy Fallon broke out their guitars for "Bob Dylan Lullabies." Willie and Korie Robertson of Duck Dynasty shared some "Tales From the Set," focusing on Willie's injuries: David Duchovny was on "Late Show with David Letterman" Tuesday night and talked about the return of "The X-Files" to TV. David said he and Gillian Anderson (Scully) will be back, as well as Mitch Pileggi (Skinner) and the Cigarette Smoking Man. (Yes!) Did David ever know they'd bring this show back? "When they developed Spanx I knew I had a shot." Still deadpan after all these years. And he looks good. Mulder aged well. He said it's a strange phenomenon that people still want to see these characters, but he's grateful. David also talked about parenting and his new album (he has a song out on iTunes - love Letterman's reaction). He has become the set-up guy for his kids' jokes. Ludacris was on "Conan" and discussed his new album, his crazy in-air marriage proposal and his beloved '93 Acura Legend. You'd think a "Furious 7" star would drive something flashier but he still drives it after 283,000 miles. He has replaced everything on it but it's dear to him. Keith Urban was also on "Conan" and talked about a disastrous attempt to play piano in the dark at a concert. It's actually really funny, he tells the story well. They also shared an exclusive video premiere for "Raise 'Em Up." Kurt Russell was on "Jimmy Kimmel Live" and talked about working with Quentin Tarantino for a second time. He said working with T is like working on a pirate ship. He got a credit at the end of "Kill Bill" and he explains why. Kurt also talked about working on "Furious 7" and his crazy mustache. The stache is for the Tarantino Western. Jeff Ross was on JKL and recorded a comedy special at a jail. Jimmy also had a game called "Don't Talk Into This Mic and Win $10" "Undateable" actor/comedian Chris D'Elia was on "Late Night with Seth Meyers" talking about Justin Bieber's roast. He had a lot of Selena Gomez fans reach out to him on Twitter ahead of time, demanding he leave Selena out of it. So he wrote Selena jokes.
