Do you want to mop the floor? You have to mop the floor with water, get some dirty water, pour it on the nearby floor, and then drag it around.

Or find a little boy to pee next to him.

Or get an electric heater to blow hot air next to it

If not, put up a notice saying that there is a mental patient. Who knows where he lives? Print photos.

Do you have the phone number of this person or his family? Internet phone harassment, okay?
