Contender for blockhead of the decade???
I reckon my mate's next door neighbour is a contender for blockhead of the decade. A few years back he was doing some renovations on his house. One of the tasks to be completed was putting a door through a wall where no door had been before. He removed the cladding where the new door was to go, thus revealing the wall frame beneath. Some of the framing needed to be removed to make way for the door but this bloke didn't have what he thought would be an appropriate saw for the job. He decided he wouldn't let that stop him and proceeded to remove the guard from his angle grinder and fitted a circular saw blade in place of the grinding disk. He fired up the angle grinder/circular saw and started cutting. While holding his "homemade saw" above his head to complete a cut the circular saw blade "grabbed" in the timber frame and the angle grinder kicked towards him. The circular saw blade ended up buried in his forehead. The bloke lived but he wasn't good for a long time. I never heard whether he ended up completing his renovation.
