A widziałeś coś takiego?

1. Abonent A dzwoni do abonenta B
2. U abonenta B nie dzwoni telefon, ale zaczyna szczekać pies
3. Abonent A nadal dzwoni, i dzwoni...
4. U abonenta B telefon w końcu zaczyna dzwonić
5. Następuje rozmowa

Wyjaśnienie zagadki:

#v+
A Kansas farm wife called the local phone company to report her
telephone failed to ring when her friends called and that on the few
occasions, when it did ring, her dog always moaned right before the
phone rang.

A telephone repairman proceeded to the scene, curious to see this
psychic dog or senile lady.

He climbed a telephone pole, hooked in his test set, and dialed the
subscriber's house. The phone didn't ring right away, but then the dog
moaned and the telephone began to ring.

Climbing down from the pole, the telephone repairman found:
1. The dog was tied to the telephone system's ground wire with a steel
chain and collar.

2. The wire connection to the ground rod was loose.

3. The dog was receiving 90 volts of signaling current when the number
was called.

4. After a couple of jolts, the dog would start moaning and then urinate.

5. The wet ground would complete the circuit, thus causing the phone to
ring.

This demonstrates that some problems CAN be fixed by pissing and moaning.
