My Old boss was Scotish.
After a wee dram or two, he would tell our company visitors (particularly from the US / europe) a great story about Haggis.
Haggis have their left side legs longer than their right side legs because they only ever run round the mountains clockwise.
Years and years of evolution have caused their legs to become longer one side than the other, exacerbating the desire to run round the mountain clockwise , making the legs longer on one side than the other, and so on.
Cracks me up watching him and the visitors as he tells the story so convincingly.
