Brace yourselves, Pentaholics! Your favorite a cappella group Pentatonix appeared on ABC's It's Your 50th Christmas, Charlie Brown special this week and nailed their version of "Hark! The Herald Angels Sing." The group was accompanied by the All-American Boys Chorus, making this an especially gorgeous performance. Watch it above, and just try to avoid the holiday cheer. You can't.
