I was at a crowded party in Romania when somebody trod heavily on my toes, at which I exclaimed very loudly "My foot !". I didn't then know just how very rude that sounded to Romanians - but Mirc will ...
Anyway, Romanian is the only language I am aware of in which a word can end "iii" or have six consecutive vowels.

Actually, there was some very important personality from an English speaking country (I really don't know what he did or what he was famous for, I think he was an important politician) called "Michael Foot", who's visit to Romania was refused as the "socialist tradition" would require the crowds to shout "Ceausescu - Michael Foot".

Which, of course, was not acceptable. As far as I know, this is actually true, not a myth. But I might be wrong.
It is ?
What is the word with 6 consecutive vowels ?
Copiii is the only word that ends in "iii", AFAIK. And this is because final I is read in Romanian as "short I", or "non-syllabic I". So to make the long I, we use 2 (like in "copii" = children). But when you actually have two long I's in a row, you need to put "iii" at the end, resulting in "copiii" = the children.
And I can't think right now of a word with 6 consecutive vowels, but I have no doubt that it exists. After all, we have this sentence, which is perfectly correct:
Oaia aia a ei o iau eu.
And I could construct a longer one, I think.
And "eu" actually has 3 vowels... E at the beginning of words is the only exception in Romanian which is otherwise very phonetic. It is sometimes read "e" (like in English "bed") and sometimes "ie", like in English "yes", which is the case with "eu" and "ei".
Here's another strange phrase in Romanian:
Lalelele, lele, lelele le legau.
"lele" is a regionalism for "woman". Not a formal word, but used in certain regions of Romania.
