World's Best Illusion

World's Best Illusion is a screamer video uploaded to YouTube in July 31, 2007. The maker is user mandel94.

The video also begins with the trippy artistic image quite similar in appearance to a flower as instructions tell you to stare at the shape, until its too late that the video suddenly cuts to a screamer. Instead of anything scary, a normal bespectacled man appears along with a funny high-pitched sounds. However, after the credits, but suddenly, a picture of a face from What's Wrong? will appear along with a high pitched scream.
