An interesting little tidbit about the Polish language: it is possible to add a suffix to the woman's last name (i.e. her husband's name) to put the name in the feminine form. At the same time, the suffix makes the woman sound like she's the property of the man. In this case it would be "Wentz" - "Wentzowa", the latter basically describing "the female belonging to Wentz". (I assume most Polish speakers don't see it that way, but I cringe every time I hear my Granny refered to by her last name like that.) (This tradition is dying out, though, as far as I can see.)

I also love it when women refer to themselves as "Mr. Peter Wentz" etc.
