Who the fuck is critical bill?

One of the benefits of taking an internet pseudonym from a popular Hollywood film is that you get to share it with all sorts. There aren't actually that many criticalbills out there, but there is this lot of Detroit rock-rappers. They've been teasing me for ages with a t-shirt that says "Who the fuck is criticalbill?" but whenever I've tried to actually see it, I've come back empty-browsered. Maybe I should make it and sell it to them. Anyway in the spirit of name-sharing promotion, here's a rather jaunty ditty by them, accompanied by a tasteful, bauhaus-influenced video, called My Sewer Side. At least that's what I think he's saying. I wonder whether MTV would film me and them doing a life swap.
