Watch Stephen Colbert and Neil Patrick Harris Make a Christmas Carol Extremely Terrifying

Neil Patrick Harris is a man of many talents. He can act, sing, dance, and make absolutely anything sound scary.

When Harris stopped by The Late Show on Wednesday, he showed off his multi-faceted talent by transforming a joyful Christmas carol into an ominous tale of doom and woe. Stephen Colbert joined Harris in the frightening fun by turning off the lights, cuing the creepy music, and intoning, “Dashing through the snow.” Harris continued with a sinister, “In a one horse open sleigh.” It got even darker from there with peals of maniacal laughter and an overwhelming sense of terror.

The performance even frightened the performers with Colbert admitting he was terrified, while Harris nodded, “I got shivers.” Colbert couldn’t let him have the last word, though: “I s— my pants. Merry Christmas!”

Harris used the nefarious performance to prove that he definitely has the chops to play the villainous Count Olaf in Netflix’s upcoming adaptation of the Lemony Snicket books, A Series of Unfortunate Events.
