Hack my Website!
Alright, this doesn’t have anything to do with Photoshop but I found it today while browsing and thought it was too cool. 
Go to any webpage (try it out on this one!), delete the url in the address bar, and copy and paste this:
javascript:document.body.contentEditable='true'; document.designMode='on'; void 0
Now try to click images/move them around, edit the text …
The results are not permanent of course. 
Neat little trick!
