[ WP ] Everyone is born with a unique tattoo on their ankle . Whenever you 're responsible for someone 's death , a copy of their tattoo appears somewhere on your skin . Your best friend 's tattoo just showed up on your wrist , even though your best friend is alive and sitting right next to you .

`` You took a spore print of these mushrooms, right?'' 
 
 `` Of course I did, man,'' said the man with the mushrooms. `` Would I lie to you?'' 
 
 `` Why are you scratching at your wrist like that?'' 
 
 `` It's nothin', man.'' 
 
 The first man grabbed the other's wrist, and saw his own tattoo on it. `` You've killed me, you bastard!'' 
 
 `` I'm so sorry, man! It showed up half an hour after you ate'em.'' 
 
 `` After I ate'em? You ate them with me!'' 
 
 `` I'm sorry man. You're always so worried about it, and it makes me paranoid. I ca n't trip like that, yo? So I always eat fake ones with you and then I do them myself if they're good. I did n't mean --'' 
 
 The first man was n't listening anymore. He was rolling up his sleeves. And there, in the same spot of his best friend's wrist, the man with the poisoned mushrooms could clearly see his own tattoo.
