A pretentious professorial goose tries to school a younger goose on animal plurals.English collective nouns for animal groups are notoriously irregular. When monocle-wearing, bow-tied Bruce pompously instructs, "Two goose is geese," boisterous young Bill responds, "And two goose is geese!" (But as Bruce realizes, two moose are not meese.) Bill always looks elated, while Bruce appears harried. Seeing leaf-bearing ants in single file, Bill guesses logically they're a herd-but no, they are a colony. As Bill sinks headfirst into a huge anthill, only the goose's lower half showing, Bruce exclaims in exasperation, "I can't take you seriously if you will not wear pants!" Sheep multiply over four pages, but one or many, they remain sheep. A group of bats is a cauldron; multiple giraffes are a tower. After readers learn about plural monkeys, fish, penguins, and pigs, teacher and pupil face a skulk of playful foxes and their stolen "socks-es." Suddenly, one fox contemplates Bruce not as a source of knowledge but as dinner-but it's Bill to the rescue! Stuart wrings humor from the absurdity of grammar rules and from the interactions between the two geese. The animals are depicted in cartoon style, with expressive eyes and jointless bodies, Bruce with a flat head and geometric neck. The pages have bright, flat-hued backgrounds, and the cavorting animals are given close to their natural coloration.
