What you need to attend Anatomy class This is the first class of Anatomy. A professor decided to teach basic things about anatomy. ""Class, there are two things you should have to attend this class."" ""First, you should be brave. Overcome fear."" Then, the professor put his finger in anus of a corpse. After that, he put his finger to his mouth and sucked. Students are shocked, but they really wanted to learn the anatomy, so they put their finger to anus of a corpse and sucked that finger. A student asked the professor. ""What's the next thing? I think I can do anything. I sucked my finger that touched a corpse's anus."" The professor said ""You are not a person to study this class."" ""Why? I overcame my fear!"" ""The second thing you need is sharp observation. I put my middle finger to anus."" ""BUT WHAT I SUCKED WAS MY FOREFINGER.""
