I had one of those, I would record moans and rewind the tape to go up to the houses, I would put the cassette in the children's rooms and put moans in the houses that had ordinance, then I would hear the mothers punishing the child for the moans, then I would get off and run away, sometimes I almost got caught, stop when I found out that some people wanted to find the idiot to make him pay, it was fun.
