I thought it was Chris Rock's fault at first, but then I saw it in its entirety and it was either staged or Will has a problem. Rock said something about Jada and 'GI Jane II' (maybe without realizing she has a form of Applica) and that's what triggered Smith. Someone on my facebook thread said there's a conflict between the two going back for a while. If it was staged (from all indications, it wasn't), it may or may not have increased viewership. A friend of mine said it was Smith's fault, another said it was CR's fault. I think it was both.
