Ice, Ice, baby, you're harshing our mellow with another dope-y Friday flick. In the third installment, Craig and Day-Day (Cube and Epps) take jobs as strip-mall rent-a-cops after they awake on Christmas Eve morning to find they've been robbed -- rent money and all -- by ''ghetto Santa.'' Sadly, there aren't too many worthy tokes, er, jokes, save for a pint-size pimp, a Jheri-curled Casanova, and a randy prison parolee. It's one thing to be wasted, it's another to have your time wasted. Monday never looked so good.
