Joke: Doggie Predictions |
It's common practice in England to ring a telephone by signaling
extra voltage across one side of the two wire circuit and ground.
When the subscriber answers the phone, it switches to the two
wire circuit for the conversation. This method allows two
parties on the same line to be signaled without disturbing each
other.
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:
1. A dog was tied to the telephone system's ground post via an
iron chain and collar.
2. The dog was receiving 90 volts of signaling current.
3. After several such jolts, the dog would start barking and
urinating on the ground.
4. The wet ground now completed the circuit and the phone would
ring.
Which shows you that some problems can be fixed by just pissing
on them.
