Dismayed Kansas City Chiefs personnel told reporters Monday that backup quarterback Brady Quinn had mistakenly received a copy of Arnold Lobel's children's picture book Frog And Toad Are Friends instead of the team's 54-page playbook. 'Brady kept talking about how he spent hours each night poring over the book and memorizing the diagrams in it,' Chiefs head coach Romeo Crennel said of the Caldecott Honor book, which is designated level two in the 'I Can Read' series and is intended for 'readers who are increasingly confident, but still need some help.' 'It wasn't until he started telling little stories in the huddle about coat buttons and ponds that we realized something was up. He does seem to have learned some important lessons about friendship from the book. He's more communicative on the field, and he's sharing the ball better, but he's much further away from being game-ready than we thought.' At press time, Quinn was preparing for Sunday's season opener against the Atlanta Falcons by carefully studying footage from the second season of Yo Gabba Gabba!.
