Watch Hall of Fame Grinch Bill Belichick Sings Classic Christmas Song

New England Patriots head coach Bill Belichick -- yes, Bill Belichick -- is full of Christmas joy.

It's hard to believe, considering the infamously grumpy Belichick is well-known for making facial expressions that can be translated as "I wish I was anywhere but here" and rarely answers questions beyond two syllables.

That's what makes this video so perfect. Someone who knows Belichick's rep well and has too much time on his hands spliced together words from Belichick's pressers to make it appears as if he's singing "Have Yourself a Merry Little Christmas.".
