Kid I know works as a prison guard and told me one time a disgruntled inmate took a dump, diced it up, and mixed it in w/the pancakes at the prison. Said they were chocolate chips. People ate them including some of the guards...why would the guards eat food prepared by inmates!?!?!?
They make the license plates here in MA, I guess the same couple of guys have been making them all for decades and it's pretty much an unobtainable job. Back in the 60s (1963 I think), disgruntled prisoners peed in the paint for the new license plates making it pretty much useless. This was before aluminum plates, and all the plates for that year pretty much faded to being illegible, then rusted out completely...it's rare to find a nice 63 plate now.
