It's worth pointing out that the Last Week Tonight clips that you see online are generally the second half or so of a longer-running HBO show: you only see the main story, and it generally comes with a spectacular call-to-action at the end (it's an intentional decision about what note to end the show on).

So the ratio for the full show is less 50/50 and more 25/75, which is much closer to your sweet spot.
