Father assist during baby's delivery

In the back woods of Scotland, Ian's wife went into labor in the middle of the night, and the doctor was called out to assist in the delivery.

To keep the nervous father-to-be busy, the doctor handed him a lantern and said: "Here, you hold this high so I can see what I'm doing." Soon, a wee baby boy was brought into the world.

"Whoa there Ian!" said the doctor. "Don't be in a rush to put the lantern down...I think there's yet another wee one to come yet."

Sure enough, within minutes he had delivered a bonnie lass.

"No, no, don't be in a great hurry to be putting down that lantern, lad...It seems there's yet another one besides!" cried the doctor.

Then Ian scratched his head in bewilderment, and asked the doctor: "Do ye think it's the light that's attractin' them?"
