Dinosaur snob

Last night Sadie and I were reading before bed. She had picked out the book When Dinosaurs came with Everything. The book is about a little boy who discovers that he gets free dinosaurs wherever he goes...free stegasaurus with a dozen donuts, free pterosaur with a haircut, etc., etc. We came to a page which showed a duckbill. She looked at the picture for a moment and said "Mom that dinosaur has a crest on his head. It's not a duckbill, it is obviously a parasaurolophus!"
