Saeid Mohammadpourkarkaragh. Yes, really. The top comment:
Karkaragh is a region in Iran’s Ardabil. It was a common practice in Iran when they started the new naming system to attach person’s place of birth to their last name. That was probably in his great grandparents’ time but the name of course lives on. I have many friends with long city/town/village/area names like this in their last name. Some opted for dropping it since as you can imagine it could be troublesome. And also it’s a separate word from Mohammadpour (which itself is a combination meaning “Son of Mohammad”). NBC probably ran out of space and had to contract it into one word.
