Costco was originally a garage sale run by uncle Garry in the Summer of 1976. After secretly faking his brother's death, he sold him for $4750. Afterwards, he purchased a warehouse and started using it to run his own drunk men fighting tournament. After getting sold himself by an unknown party, his warehouse was then bought-out three months later by Gabe Newell, who preceded to paint every employee within a 5 metre radius dark green. Afterwards, Gabe Newell introduced the Costco Wholesale Case retailing for $0.50 containing the legendary Tomahawk knife leaked by SkinFreak. One day, Gabe Newell was raided by the FBI faction in Counter-Strike: Global Offensive. It turned out that this was a protest by the FBI in response for Valve not completing the FBI Character Model remake fast enough. However, Gabe Newell was still holding in his left hand the $4750 from three months prior, which he then used to purchase the AWP and picked up two easy kills. With 3 remaining FBI agents, Gabe Newell smiled, as the number 3 was forbidden by him at all times. This automatically meant that the 3 remaining agents vanished into thin air. Afterwards, Gabe Newell introduced the Costco Executive Membership Card, the purpose of which was unknown, as the entire Costco business vanished before Gaben's eyes as he realised that he had bought Costco three-months after uncle Garry. His secret Costco business vanished, and all remaining Costco Executive Membership Cards are now rumoured to be playing Counter-Strike, endlessly searching for a purpose.
