Didn’t Hit the Mark
This might have gone wrong on a number of different levels. In a nutshell, this guy got lucky twice. To begin, this nail may have caused serious injury to his feet. Second, because it is rusty, the likelihood is that he contracted a bacterial infection. Eek!
It appears as though the nail has just pierced the dead flesh on his ankle. Ironically, it appears as though poor foot care can really be a lifesaver.
