What do sheep count when they can't sleep?

I’m someone who asks a lot of questions. Most of the time I don’t even want the answers but you can tell a lot about someone by their reaction to a question. I love asking the directions for somewhere that doesn’t exist. If you’re lucky enough to ask somebody who has lived in an area for a long time, about a non existent place, it gets really interesting. I recently went into a musical instrument shop and asked if they had the new guitar strings from Apple called the iChord. The assistant was baffled that he hadn’t heard of them and rang his supplier to ask when they would be in stock! After attempting to sell me another brand of strings, he found the website address for Apple, told me I could probably order them online and promised to have them in stock when I next visited the shop. The one question I want you to answer is: Why is a person who plays the piano called a pianist, but a person who drives a race car not called a racist?
