Boy, I wish I had this option when I lived on Four Mile Run:

The people, who live in one of Moscow's apartment blocks, were infuriated with the unceasing and irritating sound of the car alarm outside. Someone, who was desperately seeking silence and tranquility, dropped a sink down on the car. The car owner is grieving, but his neighbors are happy to enjoy the silence.

We used to play "baseball toss" from our 9th floor dorm window in college, and it was no mean feat to get something meant to be thrown to the right person on the ground*. Kudos to the marksmanship of whomever did the deed.
