So last month, on July 13th to be exact, a Canada man decided it would be a brilliant idea to kill a mouse with the butt-end of his hunting rifle. So, it turns out the gun was loaded, the man rammed the butt-end against the mouse, missed, and the gun misfired (appears it was loaded). Luckily, the man only grazed his forehead, this could have been fatal, and all because of one mouse.
