We Scots weren't to clever on this front as in 1349 we gave it to ourselves by invading England which we reckoned was weakened by plague: -
'The Scots, hearing of the cruel plague of the English, declared that it had befallen them through the revenging hand of God, and they took to swearing by 'the foul death of England' - or so the common report resounded in the ears of the English. And thus the Scots, believing that the English were overwhelmed by the terrible vengeance of God, gathered in the forest of Selkirk with the intention of invading the whole realm of England. The fierce mortality came upon them, and the sudden cruelty of a monstrous death winnowed the Scots. Within a short space of time, around 5000 of them had died, and the rest, weak and strong alike, decided to retreat to their own country.'
The men and baggage they brought back introduced it to Scotland. Karma methinks.
