I read item of Scrasamax, something with "Axtrami" in it and thought "Hey, that sounds like Pastrami". Then I thought "what the heck does Pastrami mean anyways? How is it made?", so I looked it up. And from an item of Scras' through this train of thought, I came upon this link: http://home.howstuffworks.com/question298.htm
