I’m not sure if this counts, since it’s technically suicide, but an interrogator names Mr. Wonderful slices his own arm repeatedly, while talking to the main character in the book Mogworld.
He dies from massive blood loss of course. However, nobody can die for long in Mogworld, and he walks back into the room shortly afterwards with his new body after resurrecting, and proceeds to rip an arm off the old one, and starts eating it while continuing the conversation where he left off. He also offers his captive some of his old flesh as a snack, but he turns it down, despite Mr. Wonderful being a human, and the main character being a zombie. I was literally rolling on the floor laughing at this scene.
