Jingle Bells Reversed

This is a screamer originally found on Funnyjunk in 2006. It plays Jingle Bells backwards but around 3/4 quarters into the video a high-pitched scream plays with a guy's inverted face. The original link got took down from Funnyjunk but The original owner reuploaded it on DeviantArt. Then Jeremy Winterrowd stole the link and put it on his website.
