I heard that someone said earlier that typing, "LAG!" is something to do while lagging. I completely agree with this, but I also think that people are made with a pre-brain-programmed necessity to communicate, which may be a direct by-product of sentience. There are several other occasions where this behavior surfaces as well. Have you ever been watching a T.V. show alone that you usually watch with someone else and then felt a need to exclaim some comment in regard to the previous few frames? Then, of course, you turn to look for the sentient entity to discover that the local area of space has been vacated of foreign human life. Another example is much easier for most people reading this to understand, these forums in themselves. Most of the time, this excessive communication isn't necessary. For a more specific example, how can you explain why I am just rambling on and on about a post that could have taken less than one line? Obviously, it is a combination of boredom and compulsion. So, to finally get around to actually addressing the question, yes. It is going to change something, although it has absolutely nothing to do with the computer. The change is entirely mental.
Erm... nevermind.
Yes, there is some random voodo function that typing "LAG!" engages that reduces lag.
