Don't get me wrong, I'm totally into the whole DIY culture. I also happen to love the idea of growing my own food and canning whatever we can't eat before it spoils. There have to be limits though. Without proper guidelines concerning what is and what is not acceptable some people are going to push it to far, as evidenced by this photo:
Some sick sick individual, without proper guidance, has decided to can tuna fish at home. God have mercy on all of us.
