What I'm listening to right now:
Arti Lang - Too fat to fish
Very funny and very sad. The first six chapters are read by Arti himself, then he passes it off to some of the Howard Stern cast.
Tucker Max - I hope they serve beer in hell
Very crude, very blue, read by Tucker himself. The stories don't seem as plausible when he reads them aloud for some reason.
Sarah Vowell - The wordy shipmates
Read by Sarah, it has a tremendously dry humor. It's a very funny history lesson.
David Sedaris - Naked
I thought I had listened to this (as I have all of his other books), but I've only heard half. So I'm listening to the rest of this and like his other books its great.
