If you want to do this on a node-by-node basis, you can use Drupal's core Path module. When it is enabled and you are creating a node, you should see a fieldset titled URL path settings. Insert your custom path alias there, save the node and then you can access the node from that path.

If you want to assign path aliases by a type of content (ex. for all polls have an alias of example.com/poll/#) you can use the Pathauto module. This is extremely useful for generating URL aliases. Even if you have a pattern in place for a type of content, you can always override it using the URL path settings fieldset.

You can change create URL alias patterns at admin/build/path/pathauto. For help with the Pathauto module, see the Documentation.
