Willy in simpsons

Willy in simpsons is a screamer on YouTube that was posted by user abuuh on Oct 15, 2007. The video acts like a tribute to the Simpsons character Groundskeeper Willie; it shows three pictures of him while a fast metal song plays in the background. However, the last picture is suddenly switched with the image of Regan MacNeil from The Exorcist, who pops up with a scream.
