Awesome joke, cheers.
I'm not sure why you're tagging me though. That doesn't seem like a Slovenian name (Polish or Czech, maybe?), so I've about as much of a clue as you. I looked up Przemislaw and the pronunciation I got was psheh-MI-swaf. This website has automated pronunciation recordings, but I'm obviously not responsible for their accuracy.
I wasn't able to get anything useful for Marszal. However, judging by the pronunciation of the first name and the quick look at the Polish alphabet I took, It's likely something like Marshau or Marshall.
