Not only were the producers of CSI generous enough to provide Kevin Federline with a speaking role on their hit show to help kick-start what is sure to be a celebrated acting career, it seems that they also let America's favorite background-dancing househusband improvise his own dialogue ("You bitches haven't caught them cats yet?" "Man, you're weak, weak, weak, weak."), wardrobe himself (white wife-beater, high-water pants, carefully tilted trucker hat), and perform his own stunts (getting sucker-punched in the stomach). Judging from this video clip of his upcoming cameo, their supreme confidence in the neophyte's varied talents was repaid handsomely, as Federline is utterly convincing as a sneering street punk begging to be brutalized by a cop. And based on how positively the viewing public will no doubt react to the doubled-over, wheezing K-Fed, CBS will have no choice but to invite him back for a prolonged, far more graphic televised beating later in the season.
