I've seen way more elaborate first-person joke-posts on the SomethingAwful forums, there was an incredibly long one about a guy who allegedly worked at an amusement part and how he quit his job in the most spectacular way possible.
As you read through it, you realize "the guy" is Nedry from 'Jurassic Park', but it's so cleverly written that you don't realize it until the last sentence or two.
It was hilarious.
