The greatest fan of any musician ever is so into music it hurts.  Her face is strained against her desire to rock out so hard.  And rock out she does!  If you hit play, close your eyes, count to five and then open your eyes, it'll look like she's actually the world's greatest John Mayer impersonator, THAT'S how well she knows this song.  In only 10 seconds, this video will make you laugh harder than most videos a hundred times that long.
