It used to bug me, but now it makes me laugh. Everything he says he says in a way that sounds like he thinks he's uncovering some sort of scandal: "This office has CHAIRS! It's TWO O'CLOCK! Our comrades DON'T HAVE A CLOCK!"
There was a Saturday Night Live sketch with Christopher Walken, wherein he played a psychic, but a psychic who only saw mundane things ("You will eat an ice cream cone, and it will give you one of those headaches. It's going to hurt REALLY BAD.") This speaker reminds me of that; he's like Cicero going after Cataline, except he can only accuse people of mundane things.
Is "lararium" an actual English word? My browser's spelling checker certainly doesn't think so. I think it's a word made up by historians of Rome, of absolutely no applicability to other times or places. Never mind the drunk parrots, this is the sort of word that's an utter waste of our time and brain-space. Duolingo, do better.
I guess the point is to learn that there was a household shrine in some roman homes and this was its name. Since there never was an equivalent successor, unless we count Jesus and Mary or other religious idols hanging and standing here and there, the term kept its Latin form.
