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.

Mitt Romney kicked off the late night docket with an appearance on "The Tonight Show," which was surprisingly hilarious thanks to a lil' something called Mitt in the Mirror –– in which the governor talked to his reflection (aka Jimmy Fallon). Let's just say Jimmy does Mitt even better than Mitt!

Time for another edition of Lie Witness News on "Jimmy Kimmel Live!" This time, Jimmy's crew took to the streets of Hollywood Boulevard to ask people who claimed to be March Madness fans about a bunch of random basket ball players that definitely don't exist. Prepare for lots of second-hand embarrassment.

James Franco swung by "Late Show" and chatted about the controversy surrounding "The Interview." It was definitely interesting to hear his response during this slightly tense conversation, so check it out below.

Christopher Plummer visited Conan and slayed everyone with his classiness and sense of humor. His story about working in a room full of nuns and Nazis during "The Sound of Music" was hilarious. Must-watch!

Finally, you might have heard the traumatizing news that One Direction's Zayn Malik is leaving the band. But fear not, directioners –– Andy Richter is ready to take his place! No really, just look at him sing "What Makes You Beautiful" with the rest of the group. This guy's made to be a boy-bander!
