I could still remember by the end of every fridays we would go to the school's church after school as it is required(i was in a christian school that time). One time while at the church, i could still remember the pastor to which he gave a short story and lesson about all the bodyparts(similar to the video). The body parts would make fun of the rectum calling him useless, rectum got tired of the bullying and so he did not open to the point where the body parts slowly gets poisoned from the poo that hasn't exited yet. In the end, they apologized for belittling the rectum and when the poo got released, all the body parts did not feel sick anymore. Rectum started to be appreciated after that and so the story ends. It is a story that I remember vividly and could really never forget. It stuck in my mind 'til now and it has been 6 years already, such an interesting story.
