After St Jimmy rocks your face off, Give Me Novacaine is there to give you a chance to catch your breath.

To play the intro/verses more correctly (so they sound sexier), use barre chords mainly in the higher positions except for the Bm. So, the A should be played barred on the 5th fret, the F#m minor played on the 9th fret, the Bm played on the 2nd fret, and the E on the 7th fret. Also, try to emphasize the higher notes of the chord and shy away from the lower strings.
