In the Season 4 of 4400 an episode titled Ghost in the Machine has several funny scenes that is well worth watching. The whole episode revolves around a Bill Gates-like character that is running a microsoft-like company that sells the most commonly used OS in the world and that is being attacked by a virus (ie. the Ghost in the Machine). Here's one of the funny scenes where you can see the actor does a good job portraying a Bill Gates-like persona and even blames Steve Jobs as one of the possible causes of his troubles.

If you have the chance to watch this episode I recommend it, especially for geeks this episode is great. =)
