Arcade Fire play "Little Drummer Boy" with Zach Galifianakis

Arcade Fire

If you're unlike me and your secondhand embarrassment issues don't prevent you from watching Zach Galifianakis's Funny or Die talk show "Between Two Ferns," you might already know about this week's guests - Samuel L. Jackson, Tobey Maguire, and Arcade Fire, who deliver a charmingly weird version of "Little Drummer Boy" to get in the holiday spirit toward the end of the episode. With some pretty dramatic vocals from Win and Regine, it's charmingly hilarious - check it out.
