ROCK THIS!

ROCK THIS! Chris Rock (Hyperion, $19.95) This book doesn't totally Rock, but it does roll along nicely. Right over whites, blacks, men, women, and your mama, in fact. Which is fine, because it's really just a string of stand-up pearls -- no Deep Thoughts. And somehow this equal-opportunity offender manages to come off as a nice young man you'd be proud to introduce to your parents, riff though he might on how sexy Aunt Jemima could be in a pinch (''she takes that rag off...her hair touches the ground'') or how those stale Peanuts could use Jamaican accents (''Hey, Charlie Brown, mon, le's go get some curry goat''). Cheaper than a cover charge and two drinks. B+
