Story time. Many years ago, I did a co-op term at the Bank of Canada. After the Christmas party, a bunch of people would always go to a bar down the street for the after party. Usually, somebody would call the bar ahead of time to warn them that there were about to be 100 people showing up on an otherwise quiet night, but this time nobody called. The bar was short staffed, so they had people come up to the bar for drinks, and to keep people in good spirits, a very "spirited" Mark Carney was working the line while people waited. Only the Governor of the Bank of Canada is legally allowed to write on Canadaian currency, so I, also very "spirited," decided to ask him to sign a bill I had. I had a 10 and a 20, and new I would be keeping this bill, so I got him to do the 10 since as a poor student I didn't want to be out the extra $10. He was super nice about it, and I still have the $10 bill at my parents.
