How does a grasshopper hear? What's the name for fear of the number thirteen? Who invented the umbrella? This time around, Rosten's grabbag includes fractured facts, blessed misconceptions, oddball trivia, and a multiple-choice quotation quiz--another personalized mish-mosh, somewhere between inchoate and inspired, which most resembles Rome Wasn't Burned in a Day (1972). When not expanding knowingly on octopus blood, cockroaches, or divorce, he stumps the panel with who-said-it quotes, ponders such everyday subjects as the color of bull genitals in Iraq, and responds to column readers' questions: ""Who invented Morse code?"" (Answer: . _ _ _ . . _ . _ _ . . ... ... .) Rosten can be read in any direction, especially on the bright side.
