HOLY CRAP.
I remember one time on the radio show we used to do I unwittingly followed up a Zyklon-B song with a new Vader song, and one of my friends caught it. Not only that: we were playing polka music in the background between the two songs. He called me a Fascistic turkey and said why didn't I just play an Orphaned Land song (Israeli band) too. Tank Beer would've been wonderful at that moment.
