I was eating lunch with some co-workers around the time of the Boston marathon bombing a few years ago. One of the people didn't know what a pressure cooker was, and they were showing one on whatever news channel was playing.

Another co-worker piped up with, "When I was in 5th grade my mom used a pressure cooker to clean the bones of a dead sheep I found"

Intrigued, I had him finish the story. They lived in a farm area and there was a small sheep that had been hit by a car. He took it home, and they followed a similar process to clean the bones and he used some wire to put the skeleton back together for a school science project.
