This cheerful collection of riddles introduces homonyms and other forms of word play. The riddles are clever enough for the uninitiated, ranging from the deceptively complicated--""What do you get if you throw a white hen into the Red Sea?. . . A mad, wet hen""--to the usual, though classic, transposition: ""What is the difference between a fisherman and a bad student?. . . One baits his hook and the other hates his book."" The turn-the-page-for-the-answer format, and Low's sprightly, often intentionally misleading illustrations, make this better than the average.
