Lawyer Beats the IRS
It's sort of rare, but it
happens.
On the same topic, I would like to recommend Aaron Russo's film, (available here, on Google Video)
America: Freedom to Fascism.
You can read about the theme of the film
here, on Wikipedia. Basically, it argues that the existing personal income tax is unconstitutional, as "income" is different from "revenue". NOTE: Here are some
counterpoints to certain items in the film. (Hat tip to Jason S. for the film recommendation.)
