Just for laughs...don't take this seriously, please.
Gurdial Singh's wife was expecting and the baby was due any day. Gurdial 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 the birth of his son. But in order to avoid giving a party to his office colleagues he asks his father -in-law to write "the clock has arrived" and he will understand that the son is born.
The D-day arrived. His wife delivered a cute little baby girl.
Now Gurdial's father-in-law didn't know what to do. If he writes "the clock has arrived" Gurdial will think he has got a son. If he writes "the clock has not arrived" Gurdial will get worried that something serious has happened. But being a very intelligent person, he finds a solution and sends the telegram.
Gurdial received the telegram opened it eagerly and reads "The clock has arrived, but the 'pendulum' is missing."
