LOL! Jimmy Fallon and
Justin Timberlake
Cracked Us Up on 'SNL'
Last Night


When Justin Timberlake and Jimmy Fallon announced they'd be on this week's episode of Saturday Night Live, we knew it would be hilarious - and musical!

The longtime real life friends and collaborators brought it in several hilarious musical numbers, and the women of SNL, including Cecily Strong and Kate MacKinnon, also killed it with their own original song, "(Do It On My) Twin Bed," about hooking up in their childhood bedroom during the holidays.

Below, a couple of last night's musical highlights. Which one did you like the best? Tell us in the comments!
