"Think or Don't Think" has been out of print for years now.
Ever since Arnold released "The Emasculated Male" a tale of a man with rat dogs and Eyetalian motorbikes it just wasn't feasible to keep selling mine.
You may also want to seek out his other book "In The Know" Keeping Your Ear to the Ground which is a big book about listening to dog turd's.
Finally his newsletter is a wealth of knowledge...hang on, that's not his, I was looking at Time magazine...his newsletter is actually a blank piece of paper called "Happening Things in My Neighborhood" by A Bratwurstthwacker
He has several other newsletters in the same vein i.e. they're all blank
One is called "Good Italian Bikes I've Owned"
the 2nd is "Beautiful Homes of New Jersey"
the 3rd is "Nice Places to Visit in NJ"
and the final one is "Land Manatees I Haven't Slept With" which, according to his blind neighbor, is a tour de force, not to be missed.
