Watch Steve-O Light His Head on Fire to Promote Jackass 3-D, Stay Sober

I actually can't tell what this stunt has to do with Steve-O's recent sobriety, though he definitely tries to relate the two. I suppose as long as his head's on fire, he's not doing drugs? Whatever. In anticipation of Jackass 3-D, Steve-O sets his head ablaze in front of a live audience and then has a friend spit even more flammable fluid on him. It is every bit as thrilling as it sounds. He also has a few NSFW words for James Cameron. Watch it all after the jump!
