Intensive Care Phenomenon

There was this case in the hospital's Intensive Care ward where patients always died in the same bed, on Sunday morning at 2 AM, regardless of their medical condition.
This puzzled the doctors and some even thought that it had something to do with the supernatural. Why the death? So the doctors decide to go down to the ward to investigate the cause of the incidents. So on the next Sunday morning few minutes before 2 AM, all doctors and nurses nervously wait 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 the evil. Just when the clock struck 2... Jimmy O'Leary, the part-time Sunday sweeper, entered the ward and unplugged the life support system so that he could use the vacuum cleaner.

Scottish Pocket Watch

These two Scottish characters are chatting. One of them then pulls out an expensive looking pocket watch from his pocket to check the time. "That's a fine watch you got there!" says the other. "Yeah it is, isn't it? I got it from my grandfather," says the guy with the watch. "Really?" "Yeah, he sold it to me on his death bed."
