If it's nae Scottish, it's Crap!
To make up for my Moor comment, I'll tell you a joke that makes my ethnicity look bad.
A Englishman, A Canadian and a Scotsman are in a pub. They each get a pint. A fly lands in each of their pints.
The Englishman calls the waitress for a replacement pint.
The Canadian picks the fly out and drinks the beer.
The Scotman picks the fly out, squeezes him over the glass and yells "Spit it oot, ye greedy bastard!"
