Cooper-Wheaton War

The Cooper-Wheaton War was a battle between Sheldon Cooper and Wil Wheaton. It's origins could be traced back to the 1995 Dixie Star Trek Convention, where Cooper suffered a ten-hour long bus journey of perosnal torment, only to find that Wheaton was not in attendance. This infuriated Cooper, who vowed revenge. After finding Wil Wheaton at a Warlords of Koa'a tournament, the conflict escalated as Cooper was defeated, leading to a two-year series of confrontations.

The first confrontation occured in Stuart Bloom's comic book store, when Cooper discovered that his arch-enemy was participating in a Warlords Of Koa'a card tournament. After discovering this, he immediately, much to Rajesh Koothrappali's delight, signed up to form a team with Koothrappali, who had been asking for his assistance, Cooper's eidetic memory and known habit of anticipating the outcome of a game being a decisive advantage to win the prize, $500.

During the first two rounds, Cooper's memory meant a swift victory for the team, and Cooper repeatedly ranted about his impatience to duel with Wheaton.
