If you want to make your existence slightly more irritating: Learn German and move to Germany. There the possessive s ending is written without an apostrophe - but there is an equivalent which then falsely writes the possessive with an apostrophe - the so-called Deppenapostroph (idiot's apostrophe).

What annoys me most about German vs English is that German has lots of English loanwords ending in "y" (e.g. "Party"), but it's officially not allowed to use the plural form that would be correct in English, e.g. "Parties" - you have to write "Partys". As a bonus, you could try using "Party's", but that would be incorrect again...
