They could do an entire HoG that was just joke videos and I'd still have a blast. Twists and turns make things interesting, for me at least. If it was all serious discussion, I think I wouldn't like it as much.
I truly believe we care more about the results of HoG than the Allies do. They know we care, so that's why they put a lot of effort into it, but for me, part of that effort is trying to make it interesting but also civil. 100% sincerity from everyone would be the quickest way to an actual argument that hurts people's feelings. When you keep things light and goofy, you allow for fun arguments that don't lead to any serious ramifications.
