Street fighter Kimbo Slice, who made a name for himself posting his videos on the Internet, will face former WBO heavyweight titlist Ray Mercer in the MMA cage at Boardwalk Hall in Atlantic City this weekend.  Slice has made a name for himself laying waste to opponents, and in at least one case, getting whooped by an off-duty cop, in alleyways, backyards and backrooms all the while growing in popularity via his Internet clips. Mercer reached stardom with Olympic gold in 1988 and then by reigning as the WBO titlist from 1990-1992. His knockout of Tommy Morrison is an all-time classic. As long as fights have been televised, average working class men have claimed that they could beat professionals in the ring.  On June 23, 2007 we'll find out if raw instinct can beat experience and power when Kimbo Slice faces Ray Mercer.
