Inciswf.com/cute.swf

Inciswf.com/cute.swf is a screamer website created by SparcTec. It shows a picture of a cute cat, but after about 7 seconds it shows a picture of the face from What's Wrong? in yellow along with a unloud scream, who is also the same scream when Sonic.exe kills Tails & Knuckles in the game Sonic.exe. The website then restarts. It is designed to be sent as a prank.

This screamer was parodied probably in Gravity Falls.
