5. Hanging Tree Zombie (Season 2, Episode 3: 'Save the Last One')
Andrea and Daryl stumble upon a gruesome sight in the woods – a hanging zombie and a poem of despair: "Got bit. Fever hit. World gone to shit. Might as well quit." Seems this guy tried to off-himself but didn't quite know about the "aim for the brain" rule — and naturally reanimated while still hanging in his own noose. And of course, other zombies gnawed off his lower half.
