I love playing with f12 to inspect element and change things by editing the HTML. Granted it only edits MY copy of the page buy what fun you can have, say, changing headlines on CNN, doing a screen grab and posting them somewhere else. Of course it is only on MY view and goes away as soon as you refresh, but it can be funny.

It's also how the scammers make it look like they sent you money, which is despicable, of course.

Just for you Harv!
