How can you tell a dinosaur from a peanut?"" Keep reading. A fairly large collection of riddles--featuring puns, zanies, rewrites (""Why did the [fill in the blank] wear a red t-shirt? His green one was in the wash"") and over-obvious flops in roughly equal numbers, with each question immediately followed by its punch-line. Illustrations are thick-lined drawings with gray wash that sometimes give away the answers: ""Try lifting it. If you can't, it's probably a dinosaur. (But it might be a heavy peanut)."" Uneven, yes, but a good lightweight browsing item.
