Much like lobster and oysters in Western countries, spiders entered the Cambodian menu out of necessity. During the many years of oppression courtesy of the Khmer Rouge, food was scarce to the point where the people of Skuon started to take longing gastronomic glances at the huge, eight-legged monstrosities scuttling about the area. One extremely brave barbecue party later, they found that the arachnids taste pretty danged awesome with garlic -- and the rest is history.

Why You Need It:
To conquer yourself.
By now, everyone should be more or less aware that current meat production methods are unsustainable as fuck, and there's a very real chance that we'll soon be joining the two billion people on planet Earth who are already snacking on insects for that sweet, sweet protein. So unless that guy who grows burger meat in a test tube figures out to make that shit real cheap and delicious real fast, or someone magically invents tofu that tastes even moderately acceptable (hahahahaha!), it's better to get ready for that inevitable day.
After all, it's not like arachnids and insects necessarily taste bad. In fact, people who have tried fried spider describe the taste as a cross between chicken and cod. All you're really fighting is your own antipathy towards putting deceased horror monsters in your mouth, and that instinct should be easy enough to conquer by watching a few clips of feral wild boars before your next platter of bacon. Besides, I know you. You're not about to get your ass kicked by yourself. That guy is a wimp.
