So I was mowing the lawn today on our sweet riding mower thingy and when I finished I happened to look down and see the safety warning label (ROTATING CUTTING BLADE EXTREMELY DANGEROUS DO NOT TOUCH WHILE OPERATING etc.). Below this foreboding warning was an adult figure calmly riding a lawnmower figure and running over and thusly dismembering a child figure. It was sick and funny at the same time.

So describe some outlandish warning sign you've seen. Preferential treatment should be given to those you've actually seen in real life, not just on the internet. I want factual information, consarn it.
