The word Britain! can often be the subject of many small additions, such as question marks or exclamation points. In this case, the word Britain is given a !, which essentially changes it's original meaning from a country in Europe to that of a flightless bird commonly found in New Zealand.
This bird is known to be a delicacy in many countries such as Cleveland, Uruguay, and Austrailia's more abstract living areas. Although the bird happens to be 97% poisonous, it doesn't seem to prevent these foreign cooks from cooking the three thin slivers of bird meat and selling them at outrageous prices to hungry peasants who just don't know the value of a dollar.
The Britain! can also be traced roughly back to ancient ancestors resembling the Blue-Footed Booby, the Flipda Bird, and in one odd case, Michael Jackson.
If you happen to see one of these birds, it would be thought to be quite rare, as these birds have become nearly extinct as a result of idiots buying them for their three meat slivers all over the world.
