That was really intended be a joke? Personally I don't think attempting to make a correlation between necrorobotics, and necrophilia is any more amusing then doing so between pediatrics, and pedophiles.
I'm not trying to be the thought police here, but it's a little bit to far on the depraved side to be funny to me, so I guess it seems to be an opinion thing. Please carry on, don't let me stop you.
