Anyway, an elderly lady with several pets called to say that her telephone failed to ring when her friends called; and that on the few occasions when it did ring her dog always barked first. The telephone repairman proceeded to the scene, curious to see this psychic dog.
He climbed a nearby telephone pole, hooked in his test set, and dialed the subscriber's house. The phone didn't ring. He tried again. The dog barked loudly, followed by a ringing telephone.
Climbing down from the pole, the telephone repairman found:
a. The dog was tied to the telephone system's ground post via an iron chain and collar.
b. The dog was receiving 90 volts of signaling current.
c. After several such jolts, the dog would start barking and urinating on the ground.
d. The wet ground now completed the circuit and the phone would ring..
Which just goes to show that some problems can be fixed by pissing on them. But only temporarily...
