The 37-year-old hunk, who was on The Tonight Show to promote his new movie Passengers, came up with some weird words for the game like “gnad” for a body part and “spanking” as his verb.
Pratt picked “doinkers” as his silly word and “ding dongs” for a dessert. So the outcome was always going to be strange.
The words were then used for a comical sketch where Pratt playing an angry Santa who accuses his elf Ding Dongs of stealing Christmas gifts.
The pair giggled as Fallon defended himself by saying he’d spent the night with Pickles, listening to the Roots and making snow gerbils.
But the best lines were then delivered by Pratt, who quipped: “Then why did Rudolph see you spanking on the roof?” before declaring: “The reason I work so hard is because I get to spread joy to millions of people and go sit by the fire shaking my gnad.”
The North Pole standoff left both funnymen cringing and laughing.
Check out the video for the full sketch.
