Scary Yahoo Prank
From Screamer Wiki
The Scary Yahoo Prank is a rather unknown screamer prank. When the page is entered, it looks like an old Yahoo! search engine. When the viewer clicks the search button, the page will show some search results. These will always be the same no matter what the viewer types. All the results end in "You're going to die". After a little while, the page will start shaking and the scene of David in his nightmare from the 1981 film, An American Werewolf in London, will appear on the screen with a loud scream. After the screamer is over, the webpage will reload.
