From the August 31, 2005 episode of Diddly Squat Connects the Dots. Diddly goes to the phones one last time before hanging it up for good. I doubt anyone realized that they were taking part in such an historic moment at the time.
I just discovered that in 2001, Diddly Squat created something called "The comeuppance Tape", thanks to the WebVoyage copyright archives. Does this sound familiar to you? Considering how little there is of him on the internet I doubt it's survived.
