"Moo means hello. / Moo means goodbye. / Moo means my grass is tasty. Do give it a try." Jonathan Irwin must be a bit of a translator, because here he decodes what cows are really saying, spelling it out in rhymed verse for readers and listeners up to 7. Mining the idea for all its zaniness, British artist Chris Taylor depicts a cow as he sits on the farmer, drives a racecar, tries to jump hurdles like a horse, and—for some reason—juggles some chickens while riding a unicycle.
