Pentatonix Reaction Video: "You're A Mean One, Mr. Grinch" & "Do You Hear What I Hear?" Music Videos

Finally catching up on Pentatonix Christmas content and I have two music video reactions in one video. The first is " You're A Mean One, Mr. Grinch" and the second is "Do You Hear What I Hear? ft. Whitney Houston". I know I'm months late to reacting to these, but I wanted to still do a reaction. Enjoy!
