Countdown

Countdown is a screamer video uploaded to YouTube on April 27, 2009 by Steven Anderson.

The video is a timer, counting down from 60, along with no sound until at 30 seconds, the theme song from the American game show Jeopardy plays through, and the numbers are now yellow, and still counting down till the end, When the timer runs out, the screen will begin to flash and a buzzing sound will play for 2 seconds, at which point a picture of Regan MacNeil from The Exorcist will appear with a generic, normal female scream, the video is designed to be a prank to trick people for using this as a countdown for anything, the video has accumulated over 300,000 views.
