People should not ask questions they do not want to hear the answers to. If you are going to ask 'Why do they cut the people in a y-shape when dissecting them?' you will have to brace yourself for the answer 'Well, the skin can be folded back well that way. If they only use one one long cut in the middle, you would be able to fold back any skin now, would you?' and not squirm about as you make disgusted noises.
P.S. This is what happened when my mother asked me the above question. Not sure why I'm posting it, but it is the middle of the night and I am finding it quite amusing. Might regret it in the morning....
