Approximately one third of the population is unable to 'get' or pronounce (or spell) my given name of Rolf. For some reason they are all able to get Rolfyboy (lots of 'Honeymooners' Norton-wannabees: "Hey, hey, hey, Rolfyboy"). So I stay Rolf and use Rolfyboy or Rolfy just enough for the challenged audience people to connect with.
