Towards the beginning of Groundhog Day, Phil Connors gets into the shower. The water is freezing. He jumps out. A minute later, he encounters the innkeeper in the hallway.
Phil: Yo, ma'am. Isn't there any hot water?
Innkeeper: (laughing) No, there wouldn't be today!
Phil: Of course not. Silly me.
Why wouldn't there be hot water on a particular day? Does it have to do with the weather? I've lived in sunny California most of my life, and water temperature isn't much affected by outside temperature.
