What's the worst part of having a daughter with cancer? You can't pull her hair while you rape her.
That's a pretty horrible scenario to imagine. What are you thinking?
Obviously it's a joke. You can wear a wig while you're getting chemo.
It is not a joke when are referring to the rape of a minor or anyone else for that matter. Adding in cancer to the humor isn't humourous either. Keep you humor tucked away for non-serious subjects.
