2013 Darwin Awards #4:

Seems an Arkansas guy wanted some beer pretty badly. He decided that he'd just throw a cinder block though a liquor store window, grab some booze and run. so he lifted the cinder block and heaved it over his head at the window. The cinder block bounced back and hit the would-be their on the head, knocking him unconscious. The liquor store window was made of Plexiglas. The whole event was caught on tape.
