We used to have Paul Szczechura about 15 years ago and, on a bit of a more dour note, I'm also remembering Polish doctor Zygmunt Klukowski who kept a diary that was cited frequently in a book talking about life in Poland during WWII. He lived in a town called Szczebrzeszyn.
I feel like there's two languages that abuse the letter Z. One is Polish, the other is Hungarian. I should know, my last name is Hungarian (but has no Z's). I can't explain being able to tell the two apart, it's just kind of a "know it when you see it". You're a Liverpool fan, right? I didn't need to have seen him play for Hungary in the Euros to know Dominik Szoboszlai was Hungarian. (He's also the only name in this post I didn't need to copy-and-paste into here, I actually memorized that spelling).
