Hi Dom,
It's a so called "Easter Egg".
A hidden "joke" from the developers.
You can find some more info about them here:

Also, these have been discussed in a lot of topics. When you do a search for "easter eggs", you will find enough info.
So I am closing this topic. I trust you understand.
Regards,
Fred
