SAN FRANCISCO — It could be some of the most expensive bathroom graffiti in history.

Arizona copper miner Angela Aguilar was forced to observe a vulgar drawing of herself, along with the words "put your penis here" every time she used the mine’s portable toilet. The mine’s failure to get rid of the graffiti, plus some unwanted sexual advances by Aguilar’s supervisor, led to an $868,751 sexual harassment verdict.
