There was a story I heard recently of a flipper doing this and saying they were a single mom, and negotiating a lower price.

Just as a counterpoint, we will not have any water sometime after 100 million years to 1 billion years. (I've seen a lot of different estimates, which seem to keep getting revised to shorter and shorter times.) Of course we'll have a bigger problem long before that as at that point the surface will be hot enough to boil the water away, which is way beyond what we can survive.

Is that a horror movie?

I did suffer while watching it, and it caused memory loss, as I remember nothing about it.
