I watched the whole OP video. It wasn't a waste of my time because it was hilarious. I can use a laugh like that.
It just goes to show that there are no limits to comedy. You can make a joke (or at least make people laugh) with any subject - racism, violence, child molestation, profound ignorance, genocide, etc. The list is endless.
This is why comedy should never be censored. Anything can be funny when you know how to present it.
Of course, I'm not sure she realized she was being funny...
