One of the most twisted Christmas songs of all time, "You're a mean one, Mr. Grinch" was originally performed by Thurl Ravenscroft for the iconic How The Grinch Saved Christmas. Iconic vocal group Pentatonix did their own rendition of this hilarious tune. With just a half year until Christmas, it's time to get into the mood.
