Welsh Cakes were originally baked rock hard and used as weapons against English invaders
The English have never been interested in Wales, what with its unpronouncable place names and close choral singing, and have never tried to invade. The English were in fact merely trying g to find a shortcut to get to Ireland for the Guinness.
Nevertheless, invasion has hever been far from the minds of the Welsh. Prior to 1939 Welsh place names were fairly normal, like Jonestown and Taffyville, but fearing that Hitler had his eye on the place they erected thousands of sig s with stupid, unpronouncable names in order confuse the invading Nazzie hordes. Following the war the Welsh, being a chronically lazy people, never bothered changing the signs back and the daft place names stuck.
