title: How can I dynamically download and run a javascript script from a javascript console?
body: <p>Is there a one-liner I could execute in a javascript console to download and execute a javascript script from a remote source?   </p>
  
  <p>I was looking to see if there was a nice way to download <a href="http://code.google.com/apis/ajaxlibs/" rel="noreferrer">this script</a> and use it for experimenting interactively on random pages which may not have say, jQuery loaded.</p>
  
  <p>[edit: I'm aware I could dynamically create a script element but is there a nicer way to do this?]</p>
