Adobe After Effects Easter Egg - Sheep Sound

Create a new composition. Then add anything to the stage (solid will work fine).
Goto your 'Effect Controls' panel (Window->Effect Controls)and you will see your comp name (Comp 1) and the name of the item you just created. (ex. Comp 1 * Orange Solid 1)
Hold 'Shift' and mouse click just to the right of the words. If you did it right you should hear a sheep sound.
