Someone did answer “Black Beauty”. But the correct answer was “The Black Stallion” - which the clue listed as “maybe the second-best known horse tale with black in the title”.
I wouldn’t say you have to have any religious observance, Bible knowledge, or identify as Christian to have heard the phrase “born again” in the context of Christianity.
Maybe they were too young to heard of Seattle Slew – but triple crown? Washington State? OK not SUPER obvious, but I figured it out.
I also knew “chrysanthemum” is connected to the Japanese throne.
You asked to fill in a phrase in a Bible verse, not to have just heard the term “born again.” Not sure why you are being so difficult in this. The beginning of the Lord’s Prayer is way way way more well known that the other verse you quoted.
After having recently finished watching the entire run of Star Trek:TOS, I’m ashamed I didn’t come up with Chekov.
I had no response. I was trying to think of lead characters, but that’s no excuse.
I had yesterday’s Final Jeopardy spoiled. I went to the J-Archive site to look for something, and the front page already had that day’s FJ clue visible, except I didn’t realize it was for the show that would be on that evening. I read the clue and said “who is Checkov?”
So I did get it correct, but not under game conditions.
