When Mikey's dad has a "dinosaur day", he doesn't go to work, doesn't take a bath, and doesn't know how to read. But he does go to school with Mikey and eats pizza for dinner, and has stories read to him. By bedtime, Dad's had a break, and they've both had a blast. Dinosaurs and small boys burst from the pages of this zany cheerful, full-color picture book.
