so credit to @limsup for finding this and pointing it out.
I'm not sure how long this has been in the map, but its a great homage to Old Ren. its an audio clip near the Communication center. Maybe most already know about it?
I had to listen to it like 10 times to understand it, but thats because it refers to some dude mocking @Aircraftkiller back in 2003 lol
