Irish vs Scotish trash talk from the movie "Kill the Irishman"

Potato eater?... well given the fact that potatoes were Ireland's main food source at the time and over a million people died during the famine, I'd say that comment was rather insensitive. Anyway since we are on the subject of culinary tastes, Mr McLeish, your Scottish ain't ya? Lets talk about haggis. You know it's mainly oats and lard wrapped in a sheep''s bowel? Well maybe you can talk about me being a potato eater when you stop eating fat from a sheep's asshole!
