A woman was complaining to the neighbour that her husband always came home late, no matter how she tried to stop him.
"Take my advice," said the neighbour, "and do what I did."
"Once my husband came home at three o'clock in the morning, and from my bed, I called out, 'Is that you, Jim?' And that cured him."
"Cured him!" asked the woman, "but how?"
The neighbour said, "You see, his name is Bill."
