1982: On 4 February, David Grundman drove out of Phoenix into the Arizona desert with one of his buddies, lots of beer and a shotgun. After a few drinks, Grundman began taking pot shots at saguaro cactuses. The smaller ones toppled over, but a big old saguaro stubbornly refused to fall. Grundman poked it with a stick. That dislodged an arm and then the whole cactus – more than a tonne in weight – wobbled and crashed down. Unfortunately for Grundman, it fell directly on its tormentor.
