I think that jokes should be made a legitimate part of the digitrad. They are more like 'folk' music than a great deal of the music posted there. What few I know come from them having been told to me (which is why I have so few to tell back since my memory for the spoken word is ... ahh, well YOU know!). This is oral tradition! (or in this case written/oral tradition)
Not wanting a thread creep, just consider what I'm trying to get accross.
