I'm a Punk in Drublic guy, myself. I remember seeing NOFX during the Heavy Petting Zoo tour and they threw blow up doll sheep into the audience. My brother came home with a Heavy Petting Zoo shirt, which my mom immediately banned. Great band.

Of course it probably means none of those things. My dreams of being a detective are slipping through my grasp.
