Late one evening, during a terrible storm, a man brought his pregnant wife into the maternity ward. The wife was well into labour when the power went out.

While they waited for the generator to kick in, the doctor handed the father-to-be a torch and said, “Hold this up high so I can see what I am doing.”

Soon, there was a loud cry and the doctor announced, “It’s a boy!”

The man went to put the torch down and cradle his newborn son.

“Whoah there,” said the doctor. “You don’t want to be in such a rush to put that torch down. I think there’s another baby on its way.”

The man was surprised. He hadn’t been expecting twins, but sure enough — within minutes — the doctor delivered another baby.

“A girl!” he cried.

The man was overwhelmed and went to put the torch down again.

“Hold on a minute,” said the doctor. “I think there’s another baby on its way.”

The man stared in disbelief as the doctor delivered his third baby.

“Can I put the torch down now, doc?” he asked.

“Not yet. It seems there is another baby coming.”

The man scratched his head in bewilderment.

“Doc, do you think it might be the light that’s attracting them?”
