The video starts out by showing a poor, crude animation of a loading screen with a stickman that shrinks the more the loading bar progresses. Once the bar is 75% full, a picture of the beast from Doctor Who pops up along with a loud scream. This is followed by an "ERROR" screen that offers the option to retry. Clicking "yes" triggers the screamer again. The video’s thumbnail is of the monster, spoiling the fact it is a screamer. This case also occurs with Safari.
NOTE: The following video contains a screamer!
