There's a command in Linux / Unix called "sudo" which temporarily gives a normal user the power of the root user. In non-geek mixed metaphors, instead of having limited access, you have a backstage pass which lets you do absolutely anything on the system. (Of course, the command needs a password, so not just anybody on the system can run sudo and become root.) When you use the sudo command for the first time, it prints out the following message:
We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: #1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility.
Something about that just strikes me as cool. You'd never see a message like that in a Microsoft product.
