Mateusz, it's the Polish version of Matthew.
It's just hilarious to listen to people trying to pronounce it, of all the nations I've met only the Slavics were capable of pronouncing it well as well as Russians.
Germans and Dutch are quite close, but it's not perfect. Englishmen have some trouble and the French are just hilarious, not to mention the Spanish and Italians.
Want to see something even harder though?
This is my surname: ''Wajszczak'' Even the Polish spell it wrong from time to time, so it can be quite funny whenever the teacher reads the list for the 1st time.
