For the cleanup of the hog I tried to do as much as possible except for the scraping. Once we got into butchery I tried to let the students do as much as they wanted. 
Here we are separating the bladder and urethra from the hog. This is a careful process because you don’t want to get peed on at this point. This part was also pretty funny because I was so focused on safety, pictures, overall impact on students, etc. that when asked if this pig was a male or female I answered female while we were cutting off his male bits. Not my smartest moment. 🙂
Separating the anus while trying to not get pooped on. This is the delicate bit. Once this is done, it’s pretty easy work.
