DINOSAUR DO'S AND DON'TS

Putting his familiar slouching saurian through a series of exercises in manners, safety and general behavior, Hoff attempts to foist off on impressionable kids the notion that ""Dinosaurs don't gobble their food. . . stay up past their bedtime. . . cross against the light,"" etc., and that ""dinosaurs do"" such things as practice their piano lessons, flush the toilet, and take care of library books. We trust this won't be one of them.
