The above screenshot shows the Douglas Adams quote in VIM. Type :42 in the command mode to get this quote.

The apt-command for Ubuntu, Debian and Mint has had an embedded easter egg for quite a while.

If you type the help command for apt-get, you will get a hint:

apt-get help
 
. . .
. . .
  -c=? Read this configuration file
  -o=? Set an arbitrary configuration option, eg -o dir::cache=/tmp
See the apt-get(8), sources.list(5) and apt.conf(5) manual
pages for more information and options.
                       This APT has Super Cow Powers.

Type this command to see a cool cowsay styled message.

[jason@darknet:~/Videos] apt-get moo
                 (__) 
                 (oo) 
           /------\/ 
          / |    ||   
         *  /\---/\ 
            ~~   ~~   
..."Have you mooed today?"...

Aptitude also has a cool easter egg…

ubuntu ~ $ aptitude -vvvvv moo
All right, you win.
