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.​

Surprise! James Corden gifted the word yet another round of Carpool Karaoke, but this time it was Christmas themed. With appearances from One Direction, Stevie Wonder, Carrie Underwood, and Justin Bieber, this is clearly the best rendition of "Joy to the World" ever.

Over on "The Tonight Show," Jimmy Fallon told the harrowing story of how his grandmother was run over by a reindeer. She had footmarks on her forehead and claw marks on her back, guys. No comment on what's happening here, but this clip ends with #StarWarsRaps, so you definitely need to watch.

"Jimmy Kimmel Live" put together the ultimate episode of "Lie Witness News," asking people about events from 2015 that definitely didn't happen. Like, at all. Do you remember President Obama taking time off to star in a "Transformers" movie? Because these people do.

The cast of "Sisters" showed up on "Late Night" and proceeded to play with "Star Wars" action figures, one of which ended up down someone's pants. If that's not a motivator to watch, we don't know what is.

Best for last, y'all. Welcome to Conan's "Star Wars" cold open, in which the entire late night crew play characters who were rejected from the new movie. This. Is. Everything.
