"Polly Wanna Crack Your Spine", has the parrot saying stuff like "You're dead", "Get your hands off me you dirty skank", and "Get on her and stay on her". She was just the housesitter, what goes on in that household?
"Drunk Die-er": The drunk driver who was still alive and had to not only watch his organs being harvested before they took out his heart, but feel every second of it.
