The IQ Test

"The IQ Test" is a screamer video uploaded by YouTube User DanielMcCartan In February 25, 2007.

Description
As the title suggests, the video pretends to be an IQ test. It first tells the viewer to say the color a word that represents another color is in. After, it tells the viewer to watch the dot flash and count how many times it does. But the dot will take a maddening time to flash again. Besides, not long after, a picture of Regan MacNeil from The Exorcist appears along with a scream.
