Not entirely sure on what you’re after ,so:
Wales: the lovely bi-lingual country bolted by King Offa onto the west coast of England.
Welsh: The Norman name for the people who live there. It means Foreign.
Taffy: The term for anybody born west of the river Taff.
Cymru : Taffy for ‘The land of our fathers, :)
Araf wich nwar : Slow dawn Now, commonly seen on welsh mountain roads.
Taffy Bach: Your Welsh FRiend.
Now we move on to the trick bit:
Whales: A source of Oil, meat , and controversy. They are also excessively large ,this prevents them from swimming up the river Taff, therefore they are not found in Wales anymore.
As for, would you Coffee improve the Situation:
No not really .
There is some interesting Genetic material in Wales, but superior.....If they where taking their samples from the North ,then Maybe, But the south....
To explain: The North is largely still Welsh speaking,especially around English tourists, whereas the South is mostly English speaking and has historicly had a very small Gene pool.
To sample the DNA from the North would give you access to one of the oldest intact samples of european DNA to be found anywhere.
This has all the hallmarks of either Strong illegal drugs or a WTF event on the part of any Aliens that happen to be cruising by in their MK 57 star cruiser.
To sum up:
I think Wales ,hence the Welsh not Whales, have already been at your Coffee. This is what has aroused the Aliens interest.
Disclaimer:
Wales is a Beautiful Country and well worth the extreme effort of visiting.
Just like Scotland, Eire, Stone Henge......
Ummm..
You don't have any WalMarts over there, I take it...
