cowsay is a comman line tool that you can install on any Linux or Unix distro to render funny text updates as if they're told by a cute text mode cow. There are lots of options to customise the look of both the cow and the text message.

Changing the cow appearance in cowsay
From the cowsay man page:
There are several provided modes which change the appearance of the cow depending on its particular emotional/physical state. The -b option initiates Borg mode; -d causes the cow to appear dead; -g invokes greedy mode; -p causes a state of paranoia to come over the cow; -s makes the cow appear thoroughly stoned; -t yields a tired cow; -w is somewhat the opposite of -t, and initiates wired mode; -y brings on the cow's youthful appearance.
Here's an example of one of these options:
It's also possible to just specify the charecters to be used for the eyes of the cow, -e option needs to be followed by the two characters you want to see
