Wore a cap that said 'Commie', which juxtaposed with the millions of dollar he earnt from three albums etc with RATM. His comments that his band signed to Epic was because they wanted to destroy the machine from the inside, was obviously very naive bullshit.

Tom ruled on the first RATM album, what he was doing was unheard of before, even the follow up was incredibly different.
Used long words in interviews to sound intellegent.
