When you turn the computer on under my screen it barks "KEEP AWAY! THE SOW IS MINE!"
Oooh... maybe we should add some posts about the SOUNDS on our computers!!
I've had the same start up and shutdown sounds for about two years.
On startup, an old-style Cylon says, "SCAN FOR IDENTIFICATION!"
while on shutdown the computer voice from Star Trek TNG says, "Auto shutdown sequence in progress." Very apt, heh.
