You know how you think you look when you're air drumming to your favorite song? Yeah, your timing isn't nearly as spot-on as this guy's.

This video comes from Sunday's Baltimore Ravens-Buffalo Bills game and shows an old dude air drumming like a pro. He's totally nailing each and every beat of Rush's "Tom Sawyer".

Actually, the guy is a pro and a member of the Ravens' marching band. And as great as he is, look to the top left-hand corner of the video. Some guy who's out of focus in the foreground is singing along to the song.
