I was having a chat with a friend over the weekend (by phone ofc) and we were discussing the questions he had prepared for a Zoom quiz - all male participants, mid-50's.
I vetoed a few of his questions as they required a bit of very specific technical knowledge you could only know if you had good reason to by way of your job or hobbies. Then a question comes up about a US comedy series called Brooklyn 99, and I immediately said it was too obscure and I'd never heard of it. He insisted on putting it in, and told me today that every participant also said they'd never heard of it.
He keeps insisting it isn't obscure as both he, a close relative and a friend of theirs had heard of it. AIBU to tell him that as not only had I not heard of it (let alone the slightly geeky related question) but as none of the 7 quiz participants had either, it IS obscure.
TLDR:
Brooklyn 99 IS obscure - YANBU
Brooklyn 99 is well known and a perfectly valid series to include in a general knowledge quiz - YABU
