Your whole "I dress like an office drone and act respectable and then sit on forum where we discuss urethra fucking and public torture" bit still creeps me out. I bet it would creep out your co-workers even more.
If they could actually back up the song titles with, I dunno, content I would probably agree that Anal Cunt is worth a listen. The Santa song was okay, but the rest of their catalog was complete and utter shit. A minute, two minutes at most, of pure crap in each song. Wesley Willis wrote better songs than they did, and his songs were the ramblings of a schizophrenic.
