This is what can happen when you forget to register your domain name...
Price Waterhouse are changing their name to 'Introducing Monday'... and forgot to register the .co.uk address (a real no-no for a company in the UK). So someone has registered it for them and put some real insanity up.
You'll have to be quick because, despite the fact that 'Introducing Monday' is gonna have to pay big bucks for it, they won't be able to let this stay up for very long.
Enjoy it while it lasts
