An angry customer walks into a Model Railroad hobby shop in Vancouver carrying the train set he had given his son for Christmas. He looks at the proprietor and says: "I bought this train set from you and it doesn't work; it keeps derailing off the track." The proprietor looks puzzled and takes back the train set. He brightens up after looking at it and hands it back to the customer. "Sir, your train set works perfectly fine; its a CN train set."
