Does anyone know of any good tutorials showing how to tweet from Arduino using an ethernet shield?

I'm brand new to arduino, and am terrible at programming.  Practice makes perfect though so I'm looking for some sample sketches along with a tutorial that shows how to simply tweet when a button/sensor is pressed.  More specifically via the ethernet shield.


Oh look, what happend when I type "Tweeting with an Arduino" into Google.
