Spot the difference between these two images

Spot the difference between these two images is a screamer video uploaded to YouTube by Zakawat liaqat on November 21, 2011.

The video begins by asking the viewer to find the differences between two images of volcanoes, while ah-song a's Take on Me plays in the background. After about 35 seconds, a face from What's Wrong? appears, along with a loud screech. The screamer then reappears after the text: "I found a difference! Haha!", along with the same screech.
