Damn, I knew the moon was just a slice of cheese, but I didn't know that neutron stars were a dairy product, as well. The universe really hates lactose intolerant people.
They're still neutron stars though. As far as we know the only ways for a neutron star to stop being a neutron star is for enough stuff to fall into them that they collapse into a black hole, two merge to become a black hole, or if they get eaten by a black hole. Otherwise neutron stars are just about the most stable things in the universe.
Interestingly enough, the inner Layers of a neutron star are commonly modeled to have a temperature of 0K, since the extreme density prevents thermal movements
Original joke was something specific to lactose intolerance, like milk or yogurt. This anti-joke just replaces it with something that would destroy them like that regardless of their lactose bigotry.
How is it bigotry to be lactose intolerant when it's not a choice any individual can make? Being lactose tolerant isn't even a trait shared by half the world's adult population.
