I like to sing along with Metallica's The Judas Kiss while driving and staring into the rearview mirror of the person in front of me, hoping that when they look back they'll read my lips and get a little wierded out.
"Bow down... sell your soul to me, I will set you free. Pacify your demons, BOW DOWN. Surrender unto me, submit infectiously, sanctify your demons. Into abyss, you don't exist. Cannot resist, the JUDAS KISS."
