WordPress comments make me think of Rasputin, the 19th century Russian mystic.
The story goes that when his enemies wanted to kill Rasputin, they stabbed him, but he survived it. So they poisoned him with a large amount of cyanide – and he survived that too. Shooting him in the back with a revolver slowed him down temporarily, but then suddenly he rose up and lunged at his attackers. They shot him again, and then clubbed him repeatedly, and somehow he still lived. Throwing him into an icy river finally put an end to poor Rasputin.
