I am extremely interested in purchasing your fine two-wheeled machine. Unfortunately, I am currently stationed offshore on a top-secret submarine mission and cannot meet in person. I will have my ‘transportation specialist’ collect the bike once payment is arranged. Please provide your bank account, Social Security number, and the name of your first pet so I can wire you double the asking price as a sign of good faith. Time is of the essence, as my submarine only surfaces every 47 days.”
