It isn't actually intended to teach you anything about the technology in question, but it is very funny if you already know about the subject. E.g. a sample quote on security issues (if you use ActiveX controls in web pages): "The designer of the control marks the control as safe only if the control is actually safe to use. It is almost unthinkable that someone with hostile intentions would lie about something like this."
And while I'm recommending things, "Miss Congeniality" is a fun film too, which made me laugh a lot. It even has William Shatner singing - what more could you ask for?
