Jimmy Fallon Can’t Stop Laughing at Chris Pratt’s ‘Mad Lib Theater’ Santa (Video)

The dramatic scene centered on Fallon’s elf, Ding-Dongs, being accused of stealing a Doinker.

Midway through the sketch, Fallon remembered he was supposed to be doing a high-pitched voice this whole time.

Pratt’s St. Nick didn’t stay steamed at Fallon’s Ding-Dongs over the great toy heist, and the two closed out the skit caroling together.
