Supernatural ?

There was this case in the hospital's Intensive Care Unit where patients
always died in the same bed and on a Sunday morning at 11 a.m.,
regardless of their medical condition.

This puzzled the doctors and some even thought that it had something
to do with the supernatural. No one could solve the mystery as to why
the deaths took place at 11 AM. So a world-wide expert team was
constituted and they decided to go down to the ward to investigate
the cause of the incidents.

So on the next Sunday morning a few minutes before 11 a.m., all doctors
and nurses nervously waited outside the ward to see for themselves what
the terrible phenomenon was all about. Some were holding wooden crosses,
prayer books and other holy objects to ward off evil....

Just then the clock struck 11...

and then......

Santa Singh, the part-time Sunday worker, entered the ward and unplugged
the life support system & plugged in the vacuum cleaner ...
