Intelligent solution from My Friend Hardy
Hardy's wife was expecting and the baby was due any day. Hardy was
very confident it would be a boy and was looking forward to the Delivery
day. As fate would have it, he was transferred to another city and had to
join office immediately. Before going, he asked his father -in-law to send
a telegram confirming birth of his son. But in order to avoid giving party
to his office colleagues, he asks his father -in-law to write "the watch
has arrived" and he will understand that the son is born.
The D-day arrived. His wife delivered a cute little baby girl. Now Hardy's
Father-in-law didn't know what to do. If he writes "the watch has arrived"
Hardy will think he has got a Son.
If he writes "watch has not arrived"
Hardy will get worried thinking something serious has happened. But being a
very intelligent person, he finds a solution and sends the telegram.
Hardy received the telegram, opened it eagerly and reads
"The watch has arrived, but the pendulum is missing".
