"Polly Want To Crack Your Spine?", Way to Die #571, is the fifth death to be featured in "Sor-Dead Affair", which aired on February 29, 2012.
Lindsey is hired by the Mesa family to housesit for them while they head out on vacation. Lindsey is ordered by Mr. Mesa to have no guests over, but she doesn't follow their orders as she invites Mike, her boyfriend, over after they leave their house. The two of them begin making out when they hear the family's pet cockatoo muttering phrases. The Mesa's had forgotten to tell Lindsey about the bird. Freaked out, Mike leaves in anger. Lindsey attempts to offer the bird a cracker in order to make it be quiet, but instead, it flies out of the cage. She chases the bird around the house, and finally catches up to it on top of the roof. Lindsey is about to catch the bird, but it flies off and startles her, causing her to fall of the roof and crash onto a glass table on the patio below. The glass cuts and slices her carotid artery, causing her to die from blood loss. At the end of the segment, the bird, which is a cockatoo, returns to its own birdcage.
- Also called "House Pest" on the Spike TV website.
- Lindsey's death is similar to that of Perry's death in Wedding Crasher, Heather's death in Cham-Pained, Disco Bear's death in Happy Tree Friends episodes, "Mime to Five", and Handy's death in Happy Tree Friends episodes, "Shard at Work".
- The narrator says the bird was a cockatoo, but the bird used in the footage was actually a cockatiel.
