Safari
Safari is a screamer video uploaded to YouTube on January 6th, 2008 by Jeremy Winterrowd's "prankcontest" channel.
The video itself focuses on a family outing at a safari, followed by some footage of animals such as hyenas and bears, with transitions from Windows Movie Maker. a piece of African Folk music ("Chica Latina" by Jody Jenkins; from Universal Production Music) plays in the background. However, when the bear fades out, a picture of a bald, deformed zombie with no pupils appears along with the same scream from Say It. Lastly, the credits roll, showing a taunting message reading "Go change your pants now…"
The video's thumbnail depicts the monster itself, spoiling the fact it's a screamer. This also occurs with Loading Page, also by Winterrowd.
Pictures of my family
Another video which utilizes the same footage also exists, titled Pictures of my family by Screeeaammermaker. This video was posted on November 17, 2007, which is one year before the Safari video was posted. In this version, the video ends with an image of Pazuzu accompanied by a loud scream.
