Actually the Scots gave us much more than food and musical instruments. Who formed the first modern nation? Who created the first literate society? Who invented the modern ideas of democracy and free market capitalism? The Scots! Check out "How the Scots invented the Modern World," by Arthur Herman. Our American society is rooted in scotish ideals.
Only a rabid Scotchophile (is there such a word?) could call haggis 'food', and the bagpipe a musical instrument.
