i have all his audio books on cd (he is reading them, with amy assisting), and play them in the car while driving. it's fun to actually hear his voice inflections.
i miss interchanges all the time because i'm laughing too hard.
Wow, I never thought of getting him on audio book. I read "Me Talk Pretty..." last summer and loved it but haven't gotten back into him for one lame reason or another since then. I think I'll go and stick him on my wish list; he is TOO funny.
