A friend of mine convinced me to download a couple of their songs from their album Frankenstein Girls Will Seem Strangly Sexy and my god, these guys (and gals) beat ass. Kind of a fusion of System of a Down and Bloodhound Gang and very offensive. My highest recommendation.

i am also a pretty big fan of MSI; i think it's their ability to be really really weird but have pop hooks at the same time. kind of like a scatological, industrial-metal version of faith no more (my favorite band of all time).
also, i haven't heard it yet, but their lead singer, "little jimmy urine," recently released a side project called "the left rights." should be worth checking out for hardcore MSI fans..
So I bought this album as a result of Amazon's promotion, and it is, in a word, AWESOME. Much more highly recommended than the first album I recommended in this thread. Here is a video of them playing on a recent NPR 15-minute concert:
