But I want to create something new, that make me sorry for my typing. That's how my version of sl come to life.

First of all we need to install fortune, cowsay and some additional "cows" (as I'm using Arch Linux I will use yaourt):

$ yaourt -S fortune-mod cowsay cowsay-futurama

After that install LoLcat gem:

$ gem install lolcat

And create file ~/.config/fish/functions/sl.fish with

function sl
  cowsay -f zoidberg 'Your typing is bad and you should feel bad!' | lolcat
end

Have fun typing sl.
