There is, of course, my Youtube video on How to create a website in 90 seconds, but if you want to make a Drupal website, you can do it in about 180 seconds using the Quickstart project (http://drupal.org/project/quickstart). After installing VirtualBox and the Ubuntu image, you can create a Drupal site using:
drush quickstart-create --domain=mydrupalsite.com
This will download the latest version of Drupal, create a database (mydrupalsite_com) and run the installation script for Drupal. Once done, you can just type http://mydrupalsite.com in the browser, and there it is!
