Comment: "I actually called this when I was young because I was so curious. It was a poorly recorded voicemail (like a dial-a-joke type thing). The premise was just someone talking in a grumbly trollish voice in a free associative manner. Just talking about cool stuff and how he was super cool Freddy the Freak. Worth $2. Thanks dad!" - sleaziep
Somewhat vague but still, anything helps. Ill see if they answer a pm or not. Will report back.
