I used to think that the author, Steven Kellogg, who wrote children's books such as "'Pecos Bill", "Jimmy's Boa", and "Applelard and Liverwurst", was in any way related to a certain cereal company of the same name. This also lead me to believe that, maybe, if you bought one of his books, it would come with a coupon for a free box cereal.
