Every now and then you find an "Easter-egg" within development code or in this case, Terminal for Mac OS X. I have sometimes used the "sudo purge" command to clear out RAM if I think the Mac isn't doing it well enough. An example of this is when a kernal task is using 1.2gb of RAM. Garbage collection hasn't happened.

So below is the result of typing "sudo purge" into Terminal

$ sudo purge

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.

Simple thing, but it made me giggle.

By the way, you can play pong/snake/tetris on your mac by opening Terminal, typing "emac", press enter, then escape, then type "x" followed by "snake" or "pong" or "tetris".
