One question in Round One is "What Gospel contains Jesus' exhortation to Peter and Andrew, 'I will make you fishers of men'?" The announcer says the right answer is Matthew. But Mark contains the same exhortation to the identical men in
Mark 1:17. Unlike the Matthew passage, Mark refers to "Simon and Andrew" rather than "Simon, called Peter and Andrew." But it's clearly the same two guys. However, the quote in Mark is "I will make you
to become fishers of men." So you could claim Mark is a wrong answer on a technicality. I think you probably don't want to set yourself up to split those kinds of hairs.
The same incident is also recounted in Luke. But Luke only mentions Simon, not Andrew, as the recipient of the exhortation, and the phrasing is "Fear not; from henceforth thou shalt catch men" (
Luke 5:10). So Luke is a wrong answer on couple of technicalities--he doesn't mention that Andrew was also addressed, and he writes "thou shalt catch men" rather than "I will make you fishers of men." Asking a contestant to remember minor variations in wording across three different tellings of the same story is probably a little more subtle than is fair.
Fortunately, the contestant guessed "John", the one unequivocally wrong answer of the four possible.

Another small problem in Round One is the claim that the word "Hallelujah" does not occur in the King James Bible. That's really a matter of orthography and transliteration. The original 1611 edition of the KJV spelled that word as "Alleluia". But it's the same word as "Hallelujah". They're just different transliterations from the Hebrew. More recent printings feel free to modernize the spelling of the 1611 edition and still (rightfully, in my opinion) call themselves the King James Version. For example, here's the original KJV for Matthew 24:37: "But as the dayes of Noe were, so shall also the comming of the Sonne of man be." But if you buy a KJV printed in the last century, it'll say, "But as the days of Noah were, so shall also the coming of the Son of man be." It would be captiously picayune to claim that the name "Noah" doesn't occur in that verse. That said, I think most KJVs by and large retain the spelling "Alleluia" rather than modernizing it to "Hallelujah". So the question might be right on a technicality, at least until I find a KJV that uses the more modern spelling. (And I'm betting I could. And then you could claim that's not a "true" KJV and we really don't want to go down that road.)
Oh, and for the record, on the Revelation 9 question that asked what the faces of the locusts were like, I'm giving myself credit for "women". KJV says "men," but the Greek says "anthropoi" rather than "androi"--so "humans" rather than specifically "men"--and the next verse says their hair was "like women's hair." If you rule against me, I'll never watch your show again.
