John R Sample
I often see so-called placeholder names around, i.e. on credit card advertisement, and in Germany it's usually "Max Mustermann". I started to really like this name when I learned that "muster" is translated as "example". If I use the same approach in Russian, I really like the resulting "Ivan Primerny". And in English some cards do say "John R Sample" instead of boring "John Smith", "Firstname Lastname", "Cardholder", or "John F Citizen". Recommended reading: List of placeholder names by language
