Originally written in Perl by Tony Monroe, Cowsay is a talking cow that can say any words you put into her mouth. Just don't be disappointed when you find out that Cowsay doesn't really speak. Instead, it outputs the words you want it to say in the form of text displayed in the terminal or your web browser. What's the point of a talking cow, you ask? Well, it can make your screenshots more interesting, which is how most people use them. Even if you don't actually end up using Cowsay all that often, installing it and giving it a try is a rite of passage for Unix users, who have been having fun with it for over 20 years.
