"Clock has arrived"

A sindhis wife was expecting & the baby was due any day.

Sindhi was very confident it would be a boy & was looking 4wd to the delivery day.
As fate would have it, he was transferred to another city & had to go immediately.
B4 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" & he will understand that the son is born.
The D-day arrived. His wife delivered a cute little baby girl.
Now Sindhi's father-in-law didn't know wot to do.If he writes"the clock has arrived" My son in law will think he has a son.
If he writes"the clock has not arrived",d son in law will get worried tht something serious has happened. Being a very intelligent person,he finds a solution & sends the telegram.
Just read below,u will love it.
Son in law received the telegram,opened it eagerly & reads
"The clock has arrived, but the pendulum' is missing"
