Cerf certainly churns up a lot of energy in these pieces but somehow most of ""The World's Largest Cheese"" only disturbs the olfactory sense. Unless you can snicker over say, the mnemonic aids in ""How to Tell Animals Apart"" -- ""Help! the Hippo. . . Gee! the Giraffe. . .Dieu! the Dachshund."" The only display of real talent in this hodgepodgeatorium is ""A Usually Round, Red or Yellow, Edible Fruit"" which shows to what lengths one can go when one's book of proverbs is panned and it is a rather delightful poke at critics. The title story starts out about George Smith, a man lost to posterity until he changes his name to Zarathustra Smith and, now a complete seeker after the unique, starts to walk differently -- two steps with his left foot to one with his right -- breathe differently -- inhale twice for every breath exhaled. This becomes a movement which ends with a pilgrimage to the largest cheese at the World's Fair countered by attempts to blow up the Cheesemobile. Further explanation would become as ridiculous as the story.
