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."
