Brock Lesnar

Brock Lesnar, all 280 pounds of him, is ostensibly the bear, a quick, vicious and almost supernaturally strong carnivore whose athleticism makes him nearly impossible to control. Standing in opposition is Randy Couture, the comparatively weaker homo sapiens who will have to try and negate that aggression with a more substantial martial arts IQ.
It might not be the most sensible matchup for the UFC's tangled heavyweight title picture -- Lesnar is a piddling 1-1 in the organization -- but it's exactly the kind of guilty-pleasure spectacle that gives fans, for lack of a more masculine term, butterflies. Lesnar is nothing if not imposing, and Couture is nothing if not capable. Bet large on the fight and there's a 50/50 chance you'll be enjoying Top Ramen for a few months.
