Cue the nostalgia! The Tonight Show [8] host Jimmy Fallon revived an old Saturday Night Live [9] favourite during his Dec. 18 episode. He reunited with his former castmates Horatio Sanz, Chris Kattan, and Tracy Morgan to recreate their 2001 holiday performance of "I Wish It Was Christmas Today."

We last saw this skit when Fallon hosted SNL back in 2011. This time, however, the crew had a little help from someone special: Ariana Grande. The "No Tears Left to Cry" singer took her place in a Christmas sweater dress between Kattan and Jordan, and gave an occasional cold stare to the camera. Basically, she played her part flawlessly. Watch the clip above to get yourself in the (hilarious) holiday mood.
