Try an introductory Linguistics text book. Or is that just me? (Mother Tongue by Bill Bryson would be a start.)

While I don't know about Porno, you should definitely read Trainspotting, if you haven't all ready.

Why not try some explorer/adventurer non-fiction like Hillary going up that mountain fifty years ago. Or the one where Scott & Co gets hungry in the South Pole and eats a companion but tells everybody: he walked into the snow -- uhuh.

Or get blind drunk and talk to the first old person you meet (until he starts to bore you silly).

Actually a good classic is Madame Bovary by Flaubert, allegedly the best book ever written. It should be, it took him three years.

The Importance of Being Earnest (Wilde) is funny as fuck.

Or the Rum Diary by Hunter S Thompson. He's a mad fucker that one. He wrote it back in the fifties before he became a complete druggie (only an alkie, back in the day). Fear and Loathing on the Campaign Trail '72 is pretty cool if you like politics.
