Being a Professor carries its own burdens, and you end up being called "Sir" (sometimes because students don't remember your name, but not always!). Variations of this are Dr. Nargundkar if they can get the last name right. In the U.S., they pronounced 'kar' as 'Car' due to cultural limitations, or habit.
It was Gunds in the MBA class at Bangalore. Sometimes Marcus Gundolius (Roman) or Gundarkar (Ghati) too. One of my friends in Bangalore later was more inventive, and just called me Nar.
I hope I have conclusively proved to you that I have multiple identities. If I haven't, go ahead and call me names.
