Suicidemouse.avi (Lost Episode Creepypasta)

About
Suicidemouse.avi is a supposed "lost" cartoon clip starring Mickey Mouse, the contents of which is very distressing. It's claimed that the first person who watched the clip went insane and killed himself. This pasta was one of the original "lost episode" creepypastas (along with Dead Bart) that appeared on /x/, later becoming memetic.

Although there is not sufficient evidence to prove the existence of the clip, there are a couple videos on the internet claiming to be the original:

Origin
It's believed that the story originated from YouTube, when user Nec1 uploaded a video with a lengthy description containing the back story. A poster on /x/ (will need to verify with the archives later) was the original creator of that video, posting his progress in the thread. The image of Mickey was based on a real Mickey comic that involved Mickey contemplating suicide. The comic can be found here.
