ENOUGH'S ENOUGH

Trillin's fourth syndicated-column collection (With All Disrespect, 1985, etc.)--a flurry of good-natured swipes at an array of foibles that have irked him during the past three years. Trillin's targets range from fruitcake ("". . .nobody in the history of the United States has ever bought a fruitcake for himself"") to George Bush (""Some rich Eastern preppies with sailboats are fated to walk through life as if encased in a sort of tweedy cocoon. Bush is one of those""); from Michael Milken ("". . .the Gambino crime family takes in an estimated $500 million a year. That's $50 million less than Milken"") to smart cameras (""When I pushed the button, it advanced itself to the next picture with a contented buzzing sound like a horsefly that has just had a bite of something good""); and so on. The commentary is charming, pointed, and even wise, and to wrap it up Trillin offers an afterword about his fan-mail--which, he says, deals primarily with ""the fruitcake question."" Another endearingly curmudgeonly collection.
