Absent Father

Alright, listen up, chucklenut. The joke is that the person's dad LEFT them, see? And cancer? Well, cancer STICKS AROUND whether you want it to or not, like that outdated haircut of yours. It's dark humor because, well, it's about someone's terrible family situation and a life-threatening illness. If you still don't get it, maybe try staring at a wall for a few hours. Might be more your speed.
