I listened to this on audio, it was only two and a half hours long. Narrated by the author himself George Carlin.
It was entertaining... I think?
I fell asleep through the second half. I do remember before elapsing into a coma state; thinking to myself, "the second CD is much better then the first." I really am sorry Mr. Carlin that I was not able to give you my full attention, but I did hear your voice in entirety through a rather strange dream sequence. Based on the reactions of the characters of said dream, I am going to give you 3 Stars. :)
