Possum's Haystack 

n: The gnarliest, nappiest, most tangled thicket of pubic hair known to mankind.

Many different species of animals may inhabit the possum's haystack, because of the multiple ecosystems grown over time.

Nobody really knows how people become inflicted with the possum's haystack, however, experts do believe that it could possibly obtained from little to no maintenance to the "under rug" for many, many years. The condition, however, is fatal.
Reginald M. Nooker was the most famous case of possum's haystack. He did not trim his pubic hair for 39 years. His hair follicles were so overactive that they did not grow long, but thick, and tough, and they curved back and around in every possible direction. He broke many chainsaws simply trying to find his penis.

haystack 

The city of Hayward, California. It is known as the "heart" of the bay. The city was founded by a man named William Hayward, who came to California to seek his fortune in the California Gold Rush (Began in 1848, I believe). He bought some forty acres from some Rancher, and in a few years sprouted into a town. Was at one point misspelled into "Haywood". Haystack is a slang term when reffering to this city.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
