I believe Andrew WK's end goal is to make it ambiguous if he ever existed. He wants to make his own identity a conspiracy theory, because he thinks it's funny, or artistic or something. From the whole Steev Mike thing, to the times he's come out on stage identifying as the second Andrew WK, or how he'll occasionally drop off the face of the Earth. He's deliberately trying to concoct a conspiracy theory about how he's not a real person, even though he is. He wants to be remembered as this mysterious ethereal construct.
I have a hunch that the cultural association with owning a big dog as better than a small dog is an effort from dog food companies to sell more dog food.
Ken Lay faked his own death and is possibly still alive.
My pet conspiracy theory is very specific but I'm very convinced of it. I'm convinced Death Stranding and Metal Gear Survive were at one point the same game. For some background info: Hideo Kojima was the director of the Metal Gear Solid games. For unknown reasons, he was fired from his parent company of Konami in 2015, shortly after the release of Metal Gear Solid V. Metal Gear Survive released in 2018, the next game in the series. It was made without Kojima's input and is largely dismissed by fans of the series. Death Stranding was Kojima's next game, which released in 2019
I truly believe Survive was made from very early test builds of Death Stranding, including things like the basic structure of the narrative and gameplay. Both games involve building structures in large, empty areas. Both games are about managing stamina while taking long treks on foot. Both games involve collecting a crystal resource to purchase upgrades or build structures. Both games center around themes of death, parallel worlds, and connecting people. Konami 100% seized control of whatever Kojima had been working on, slapped some Metal Gear stuff and zombies onto it, then called it a day.
