`sl` also takes arguments, which change the shape and size of that damn locomotive: -a -l -F

It's a fun, masochistic joke, but I seriously encourage everyone to install it (it's available on Homebrew, if you're an OS X user). Every time you do an `sl` you must immediately resolve to be more careful when doing things on terminal. It `ls` is harmless, but what if it was `rm`?

Yay for steam locomotive! I think of it as a handy reminder from your sys-admin "don't drink and ssh!"

That same sys-admin probably won the Crash And Compile drinking game at DEF CON. Don't listen to him.
