Humour is subjective. I could name a number of popular things that are as funny as root canal surgery in my eyes like Friends, Seinfeld, James Acaster, Romesh Ranganathan. And other things that have me rolling on the floor with mirth like Mrs Browns Boys, Sarah Millican and Jimmy Carr. I love roast shows but other people find them cringe.
I get where OP is coming from, but people have a right to create threads for any number of reasons, and as long as they are not vicious or nasty we aren't going to delete them because something has tickled a number of players who have run with the theme.
Full disclosure, I love them myself, and another GM was rolling their eyes and sighing at the whole thing.
