Pr0n Tax

From this article:

"California Assemblyman Charles Calderon says he doesn't have anything against pornography. He just wants to tax it.

The Democrat from Whittier has a bill that would add an eight percent tax to X-rated products, sex shows, and explicit
pay-per-view movies."

HT: Fark Headline, the first comment on the thread of which contains what I consider to be a knock down argument against such measures: "...and I'm sure everyone will agree on a very specific definition of 'porn'"
