Can I disable the lighted Apple logo on the back of my MacBook Pro? I want to disable the light on the apple behind my screen. Besides covering it physically, is there a program or setting to disable it?

Reason being - to make my MacBook Pro as uninteresting as possible to hyperactive two-year-olds.
Nope. 

The glowing Apple on your MacBook Pro is actually illuminated by the backlight of your screen as well. So you can't turn it off as long as you have your screen lighted on. Your best bet is probably to put a sticker on it.
