A woman called the phone company to check her phone line. It seems that
her daughter complained that she had to ring her mothers phone
many times before she would finally answer. The mother said she only
heard it ring one to two times before she answered.
The repair person (politically correct) knew something was up when the
mother said she felt her dog was psychic. The dog would start barking just
before the phone would ring. He found that someone (politically correct
not to accuse) had disconnected the phone ground line and used it to tie
off the dogs chain to his metal collar.
Apparently when the call came in, the dog would get more than 90 volts
of direct current, but there was not a good enough ground to allow the
ring. The ring occurred when the dog urinated and made a good ground.
Theres a lesson there somewhere.
