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.

Time for a game of Flip Cup with Margot Robbie on "The Tonight Show!" First to chug their beer and flip their cups wins, and obviously Margot killed it. Her prize? Some toilet paper. Only the best from Jimmy Fallon!

Richard Madden showed up on "Jimmy Kimmel Live" to talk about being Prince Charming in "Cinderella," and apparently with great power comes great responsibility. And tight leggings. And zero genitalia because this is Disney, which means that Richard had to spend hours trying on jock straps. Ken dolls feel your pain, buddy.

Viola Davis video-chatted with Jimmy Kimmel to discuss the "How To Get Away with Murder" finale, and he even whipped up a handy plot chart –– which is actually pretty helpful for those of you who are confused about how everyone's getting away with murder on that show.

Of course the best part of "Kimmel" was when Jimmy weighed in on the vaccine debate. All of his musings are worth-watching, but some highlights include "parents here are more scared of gluten then they are of small pox" and "Jenny McCarthy popped up and she had clothes on so they listened to what she had to say."

Finally, Ellie Kemper hit up "Late Night" to chat about how she was Jon Hamm's theater student in high school (some people have all the luck), and revealed that everyone in St. Louis basically spends their time Hamm fan-girling all over the place.
