Cars

My son has all of a sudden formed an obsession with the movie Cars. We had really only watched it about 3 times in his little life and then about 2 weeks ago he started talking about "cahs". He's a true easterner. As soon as we walk in the door after we get home for work he starts saying "I un cahs". Over and over. He walks right to the laundry room door and tries to open it. That is where we keep all of our movies in order for him to leave them alone. I only let him watch it about 2 times a week because that is all that I can handle of a movie. So we got him a Lightning McQueen football and a little Lightning McQueen car hoping that it will help a little bit with watching the movie. So far he is never really without one or the other. I just don't understand where this love for all things Cars has come from.
