This strip pokes fun at stereotypical Linux users for having a different set of computing priorities than most people. In this case, the Linux user places the ability of his computer to have many more central processing units than necessary over being able to watch funny videos on YouTube, which is something “normal” people would want. It is implied that Linux users are abnormal. Many readers of this strip are presumably Linux users and will find this humorous because they themselves would consider themselves more advanced than “normal” people when it comes to computing.
