Not sure how YOU are closing out the year, but Jack Black is doing it right.
The actor and Tenacious D frontman shared a clip to his Instagram page of him in a speedo and Ironman mask while dancing to Black Sabbath's own "Iron Man."
You can also see Black fly down a la Tony Stark, playing with colorful flares, and grooving to the song because why the heck not?
The caption for the post? "2021 comin' in HOT!!!"
