This Craig's List entry promises to make you better at Starcraft.

I'm 100% full blooded Korean, meaning I have been gifted with unparallel talent to master any video game, particularly, Starcraft: Brood War...I'm offering my expertise in Starcraft to be taught to non-Koreans that wishes to have the skill of a Korean player. I have advised and coached many professional gamers such as Im Jae Dong, Park Myung Soo, Ma Jae Yoon, and more. Boxer and I were great friends until he started using my dropships to gain his fame. I started training other players to be on par with Boxer and eventually surpassing Boxer. He is no longer the best player thanks to my contribution to rest of the players. I did not compete in pro gaming because they KTF did not agree with my seven figure contract demand.

The hourly rate you pay to learn Starcraft skillz vary by whether you're looking for basic training, advanced training, or race specific training. For some reason, it's only $20 an hour to learn the ways of the Zerg. The rate skyrockets to $30 an hour is you want to learn the ways of the Terrans.

The lessons promise the following outcomes:

Bragging rights, that you're as good as a Korean in Starcraft
You will be called a hacker because you're so good.
Korean girls will be intrigued that you're such a good Starcraft player.

If this was any other game but Starcraft, I'd be inclined to think it was a goof. But I've seen first-hand the impact of Starcraft on Korean culture. This level of earnest isn't a stretch.
