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.

Please commence shaking, crying and flailing, because there's a new member of One Direction. And he's a potato. Soon he will be extremely famous, and in the words of Jimmy Kimmel, "might be be dating Ariana Grande." Let's just hope he doesn't get murdered on Thanksgiving.
Speaking of super famous people who teenagers are completely obsessed with (not to be confused with potatoes), Justin Bieber swung by "The Tonight Show" and got in on a super-secret handshake with Jimmy Fallon. It was...lengthy.

Over on "Late Night," Josh Hutcherson chatted about living with the cast of "The Hunger Games" in a hotel. Turns out they had an open door policy so you can imagine the hijinks than ensued, amirite?
Meanwhile, something totally amazing happened on "The Late Late Show:" Byran Cranston performed with the Grown Man Boy Band, wearing a white suit and mohawk. All you need to know is that he sang the lyrics: "I'll make love to you in my minivan." Blessed.
Finally, and also on "The Late Late Show," Joseph Gordon-Levitt kissed James Corden on the mouth. It was beautiful, so please watch.
