Well before the Blue Box era, friends had phun with pay phones.

Nice!

We used to take a wrapper from a stick of juicy Fruit gum, the foil over
paper one, put a slight curl on it so it would slide between the base and
pay phone. This worked on the older style (1960's era) pay phones. You would
slide the foil in on the right side at about the middle then slide it slowly
up and down till it shorted out the magic connections. Voila, a dial tone
and you could make a local call.

I heard reports of the 'impenetrable pay phone' (early 70's) being deployed
at Cornell University. Supposedly the phone had been removed from the wall
by the 'inquisitive' folks, reverse engineered and hacks distributed within
a day of deployment...
