I had a student (and this name is not sad) named Thomas Reynolds Lastname the Eighth (VIII)....Hope he keeps the name going.
If he doesn't, he will be the last of the Lastnames.
I had a student from Indonesia whose name was Djan Meow Liong. At the first of each semester, I called the roll by last name and ask the students to tell me what they wanted to be called (thus avoiding some embarrassing revelations).
When I said "Liong," he said, "I go by my first name."
"And how do you pronounce it?" I asked.
He said, "John."
Not knowing how the name was spelled, the rest of the class laughed.
