This is actually the worst. Just look at McConaughey's eyes. They're dead to everything.

In an attempt to get some cross-market viral action going for both 'The Tonight Show' and the movie 'Sing', Jimmy and The Roots joined Paul McCartney, Matthew McConaughey, Reese Witherspoon, Scarlett Johansson, Seth MacFarlane and Tori Kelly for an a cappella rendition of 'Wonderful Christmastime'.

For starters, 'Wonderful Christmastime' is one of the worst Christmas songs and even if you do have access to Paul McCartney, there are better Christmas songs you could choose.

Secondly, a cappella died when 'Glee' did so please stop kicking it, it's already dead.

Finally, again, look at the pain and the void in the eyes of McConaughey. You can almost see him thinking "I HAVE AN ACADEMY AWARD WHY AM I HERE". There is literally nowhere he would rather be less.

This is just upsetting on so many levels.
