Are you bored of "areas the size of Wales" (or even whales)? Then perhaps you would prefer to use "areas the size of the PRINCE OF WALES"? (Yes, this is the silly one.)

That's right - for the first time ever we are now able to offer you the chance to demonstrate the size of your subject in terms of the surface area of the Prince of Wales. Amaze your friends and astound your colleagues with this new standard!
