Easy "hacking" a web page, then email it to the webmaster

Here's a way to give your favourite webmaster a fright! Edit his web page, then send it to him via email... it will look like you've hacked his page.

Also, use it on a news site (like CNN) to make headline news of your accomplishment, birthday wish, etc...

Here's how:
1) Go to any web page
2) Clear the address bar, and paste this (without the quotes):
"javascript:document.body.contentEditable='true'; document.designMode='on'; void 0"
and hit enter.
3) Feel free to edit whatever you want on the page!
4) Then print the altered web page to pdf and send email.
