BBC News
You certainly used to be able to do this on the BBC News site. I think they stomped on it after some similar misuse.
It's hats off today to whoever it was who discovered that you can stick any text into an Independent URL, as long as you leave the terminal numeric identifier, and then used the technique to stamp on the claim that Kate Middleton had manifested in a jelly bean. In case the Indy fixes the problem, here's a screen grab of the …
Oh yeah? You should see some of the URLs I used to compose here. Nothing too fuckish but a lot of very silly stuff. It's entirely plausible that a mad-as-hell sub could have slipped this one through the net - newsrooms are busy places, you know. I'm just sorry that's not what happened.
Read the article again. Not only have you completely misunderstood all 90 or so words of it - I take it you're a shining example of our wonderful education system (that isn't getting worse, just "differently better") - but you've even failed to notice the humourous URL used by El Reg itself for the article.
In case you're from the tl;dr; generation (I know 90 is quite a large number of words) here's the short version: The final part of Indy URLs can contain any text the *user* enters, as long as they end with the article number.
Although not as good, I noticed a few weeks back that the Twitter Help Center uses the same technique and is also open to abuse, for example:

I know you think you're clever, but using the pound sign (#) at the end of a URL simply means that you are pointing to a named anchor within the HTML page at the particular URL. It is an entirely different example to changing the actual URL.

Now "Need to Know", when it was(?) running, had "Widdy of the Week", where readers would send in web sites where tampering with the URL would give you a web page whose TEXT incongruously mentions Ann Widdecombe, or any other unexpected appearance, such as (Tweeted[?] by "Giles Thomas", currently high in Google for WOTW)http://www.bestuninstalltool.com/Uninstall-Colonel-Gaddafi.html#libya
"Colonel Gaddafi Uninstaller - How to Remove and Uninstall Colonel Gaddafi?"
"Run a free scan to check for Colonel Gaddafi and related files on your PC now!
"Uninstall Colonel Gaddafi manually:
"Removing Colonel Gaddafi thru Add/Remove Programs on Control Panel is the most common way used by many computer users. Generally, you can take the following steps: ..."
The "libya" bit doesn't appear to do anything, maybe it's a non-functional flourish like yours.
Yes, mostly childish, but also a demonstration in how to make a strictly not hacked web server produce deceptive content that the owner probably would be sorry to see, and in some cases could be used for fraud or worse.
Or just to type in words like (buy grandmother) and have Google side-serve you adverts like,

Just (granny) is genuinely NSFW, I am not kidding, it really is. Don't say I didn't warn you.
