Walrus

Hello, I am currently 18 years old and I want to become a walrus. I know there’s a million people out there just like me, but I promise you I’m different. On December 14th, I’m moving to Antartica; home of the greatest walruses. I've already cut off my arms, and now slide on my stomach everywhere I go as training. I may not be a walrus yet, but I promise you if you give me a chance and the support I need, I will become the greatest walrus.

2013: Takuya Nagaya, 23, from Japan, started to slither on the floor and talk about becoming a snake. His mother took this to mean that he had been possessed by a snake demon and called for her husband, 53-year-old Katsumi Nagaya, who spent the next two days physically beating his son in an attempt to exorcise the demon, ultimately killing Takuya.[103]
