File Permissions Joke

I was browsing around my company's internal wiki while looking for some teaching aids on teaching the Red Hat RH033 course this week and next. While there, I found this fun little gem (provided by Joseph Hall):

When teaching file permissions, create a directory called 'base' and in that directory a number of base? files:

aaron@kratos:~$ mkdir base; cd base
aaron@kratos:~/base$ touch base{1,2,3,4}
aaron@kratos:~/base$ ls -l
total 0
-rw-r--r-- 1 aaron aaron 0 Nov  4 01:59 base1
-rw-r--r-- 1 aaron aaron 0 Nov  4 01:59 base2
-rw-r--r-- 1 aaron aaron 0 Nov  4 01:59 base3
-rw-r--r-- 1 aaron aaron 0 Nov  4 01:59 base4
aaron@kratos:~/base$ su -
Password:
root@kratos:~# useradd us
root@kratos:~# cd /home/aaron
root@kratos:/home/aaron# chown -R us.us base/
root@kratos:/home/aaron# ls -l base/
total 0
-rw-r--r-- 1 us us 0 Nov  4 01:59 base1
-rw-r--r-- 1 us us 0 Nov  4 01:59 base2
-rw-r--r-- 1 us us 0 Nov  4 01:59 base3
-rw-r--r-- 1 us us 0 Nov  4 01:59 base4

Now that's pretty good! Anyone who even remotely claims to be a geek better get the reference to that joke.
