My cousin bought me the audio version of this 7 years ago. I wasn't sure why, but I had heard that Dave Barry was funny. I listened to it on the way back to Sonoma County from San Diego. It was a fantastic 3 hours that took me from Mojave to just north of Fresno.
Mr. Barry has an unusual sense of humor, mixing a sarcastic wit with observation and whacky schemes to get rich and/or better the world. He takes us on a voyage from the usefulness of the word "weasel" to Disneyworld, to buying a boat, to the Nintendo world, and later topping it off with his own airline with Sean Penn as the official spokesperson.
I have to say this, though, I have had others listen to this masterpiece, and while a few liked it as well, others didn't get it and therefore did not like it. You either like Dave Barry or you hate him. As for me, I went about buying many other audiobooks of Dave Barry, as well as actual books. No 4- or 3-star review would pull that much money from me!
