Countdown

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

The video is a two-digits digital clock, counting down from one minute. It's fully silent and the number is green until reaches thirty seconds, at which point the theme song from the American game show Jeopardy! begins to play and the number turns yellow. At fifteen seconds the number turns red and under ten seconds the number starts flashing red and white. When the time runs out, the backround begins flashing and a buzzing sound will play for 2 seconds; a picture of Regan MacNeil from The Exorcist will appear right after, with a generic, normal female scream.

The video is designed to be a prank, aimed at people intending to use this as a countdown for any purpose. The video has accumulated over 300,000 views since its upload.
