Knoxville is my favourite. Although Steve-O usually does the most hardcore stuff, I love the way Knoxville throws himself so eagerly into pain and danger. Dude is nuts, it´s not like he´s just suffering, he´s doing it with passion, he wants more! lol
I wish they could drop the boring fake acts like the ones involving Bam´s parents and focus on the classic stuff, like cuting themselves between the fingers with paper (that scene makes me cringe everytime).
