I think the mockery comes from the fact that you want a national, prime time television show to book performers specifically that your parents know.
And that he keeps saying it repeatedly.
Yes, it’s also tedious, he’s made the point it doesn’t need to be repeated constantly.
Also let’s not use spoiler tags for speculation. If speculation is going to ruin it for people they wouldn’t have speculation on the show and everyone interested is going to read the spoilers anyway. Also if it was a genuine spoiler (i.e a name got leaked) the spoiler tags simply wouldn’t work because people wouldn’t be expecting genuine spoiler.
You're a "younger person", yet you complain that the show isn't catering to over 50s (or at least your/your parents perceptions of what over 50s like)...
I have to watch it with them and see their rants and deep disappointment at unknown faces being unmasked making the entire act of guessing the clues impossible for them.
