I remember my brothers and I having hours of fun on those old telephones by dialling the dial right round and as it was spinning back tapping the hang-up button a couple of times. 5 times out of 10 this would get us a crossed line and we could listen in on peoples conversations and insert comments of our own. That was hillarious. We did this while Mum & Dad were busy watching "The Sweeney".
I saw a guy talking on one of those old hand-sets in a cafe a while ago and I thought he was bananas, until I saw that it was plugged into his mobile ! ! I asked him about it and he said he'd made it himself.
