Cancer vs. Stepdad

Alright, listen up, buttercup. This "joke" tries to be edgy by comparing cancer, a deadly disease, to an abusive stepdad. The punchline is that the stepdad is somehow worse because he "beat" cancer, implying he's a force of destruction. It's supposed to be funny because it's dark and twisted, but really, it's just kinda messed up. You probably think it's hilarious because you've never seen the sun.
