Duck Tron?

So I was playing an Argos quest solo, when all of the sudden the sound clip from Duck Tron starts playing (search for Duck Tron on Youtube).

I didnt have anything else running, so it had to be from the game. Is this supposed to be some weird easter egg? I have no idea what triggered it.

|||As far as I know nothing like this is in the game. At least it wasn't in the beta/pre-release. A way to make sure it's not the game, mute Spartan.exe while running the game in Windows Volume Mixer. This way you can rule out it's the game or not.
