Angular momentum is my favorite xkcd post:
The reason this works is because the spinning is an earnest useless act by the woman for her lover. It's like a man giving flowers to a woman. Flowers are pretty much useless with short shelf life. They're worse than bananas. What matters is that he's thinking of her.
In comparison, a person sentenced to hang by the neck at sunrise until
dead wouldn't spin to lengthen the night. It would be useless
and not make an iota of difference. That the woman is doing it,
demonstrates that she would do anything for her lover.
