Barbie.avi

Barbie.avi is a story of a man who stumbles upon an old computer that is located in a dumpster. The old computer consists of a 40-minute file under the name "Barbie.avi"; the video depicts a woman (that supposedly suffered from BIID), talking and crying about her own skin. The last few minutes of the footage show a man walking on a pair of train tracks to an old abandoned house in the middle of the woods. The viewer walks around the house, (similar in one to the footage) taking pictures before he hears a moan blurting out from the pipes as he runs out.

Original Source of the Videos
The original video consists of four actual parts, showing a 20-year old amputated girl named Tammy (or Becky) talking about an accident she had with an old washing machine (she was 16 at the time); the spin cycle went off as she arranged a sheet in before it twisted her right arm off.

One of these interviews were shot around the year of 1989; they were reuploaded on an amputee website called "FreeAmputee" around the year of 2009. The downloads don't work now, despite MegaUpload shutting down. The original name of one of the files are titled as, "Tammy RAE". You can download the full .zip file here, containing the pictures and interviews.

The girl later became a Fascination model (which is no longer running).

Creepypasta Origin
The original copypasta of the Barbie.avi story was posted by an anonymous user on 4chan's /x/ around July 2009. He even posted some cropped screencaps (that were in prior to the actual footage) and two alleged abandoned house pictures. The Creepypasta was later added to the Wiki.

Videos
Here are some of the videos that are related to the pasta; they are cropped in a manner so you can't probably see her right arm and the footage clearly. One of these videos has a loud distorted buzz in them to make it hard to listen to the girl's speech. Originally uploaded by Xenopasta.

Part 3 is supposedly missing. However, kudos to a couple of Russian investigators on /x/, they have found the actual footages (including part 3) and pictures of the girl!
