Every night, little Jimmy says his prayers before going to sleep.
"God bless Mummy, God Bless Daddy and goodbye Uncle."
Jimmy's mother is shocked to hear this, and as a result, the next day she learns that Jimmy's uncle has had a heart attack and died.
The following night, Jimmy says his prayers again.
"God bless Mummy, God bless Daddy, and goodbye Granddad."
Sure enough, the next day, poor Jimmy's grandfather dies in a car crash.
That night...
"God bless Mummy, and goodbye Daddy."
Everyone is appalled and the next day Jimmy's father come shome from work in one piece...
"How was your day honey?" asks his wife.
"Terrible, I've been taking so much care with everything - when I cross a road, when I handle staplers, when I pour hot water...it's been hell trying to avoid dying! How about your day dear?"
"Awful! I opened the door to let the milkman in and he just dropped down dead!"
