As Korman proves in his funniest book to date, the trials and tribulations of producing a radio show can be sidesplitting. ""Kidsview"" airs live on a local FM station every Saturday, and it's up to fifth-graders Benjy, Mark, and Ellen-Louise to pull it together--even if the pet-shop sponsor's Mascot of the Week is flapping vigorously around the studio; the new teacher has to be kept from finding out that her homework assignments are being used for a wildly successful phone-in trivia contest; or the editorial's hysterical warnings about the dangers of ultrasonic sound have 12 second-grade choral readers ready to stampede. To add to the mayhem, sixth-grader Bard Jaworski--the huge, leather-clad ""Venice Menace""--has begun commandeering the mike each week to read a series of stories about homicidal kittens. Can Benjy--even with the example of his radio idol Eldridge Kestenbaum to sustain him--stay cool, summon the courage to cut Brad off, avoid the cardinal sin of dead air space, and keep the show on the air? Don't touch that dial!
