I guess it was just a matter of time before they had a serious mishap. Luckily no one was hurt.

The cantaloupe-sized cannonball missed the water, tore through a cinder-block wall, skipped off a hillside and flew some 700 yards east, right into the Tassajara Creek neighborhood, where children were returning home from school at 4:15 p.m., authorities said.
