How to put down your Mac machines into sleep....?

Two Seconds to Sleep (Its a Mac Magic)

Fastest way to put your Mac right into a deep, sleepy-bear hibernation-like sleep (no whirling fan, no dialogs, no sound — nothing’ — just fast, glorious sleep). Just press Command-Option and then hold the Eject button for about 2 seconds and you can see the Mac goes into sleep……..

It doesn’t get much faster than that.
