The White Christmas Game
From Screamer Wiki
The White Christmas Game is a sabotage by Liquid Generation.
It starts with the title screen, it has instructions telling you to wipe off the frost to "reveal the secrets of the season". If you press Play, a finger appears in the screen and you control it with your mouse to wipe off the frost from the window. If you wipe the window too much, Santa with a skull and an axe pops up with a rather loud screaming sound. Then text appears reading "You have been sabotaged!!!" around a red logo with the Sabotage Ninja on it while the Sabotage Ninja pops down and says "Click here for more sabotages!" Then, a link to Liquid Generation crushes him.
