The local doctor is there in attendance. "What d'ya want me to do, Doctor?" "Hold the lantern, Mikey. Here it comes!" the doctor delivers the child and holds it up for the proud father to see.
"Mike, you're the proud father of a fine strapping boy." "Saints be praised, I..." Before Mike can finish the Doctor interrupts, "Wait a minute. Hold the lantern, Mikey." Soon the doctor delivers the next child. "You've a full set now, Mikey. A beautiful baby daughter."
"Thanks be to..."
Again the Doctor cuts in, "Hold the lantern, Mikey, Hold the lantern!" Soon the Doctor delivers a third child. The doctor
holds up the baby for Mike's inspection.
"Doctor," asks Mike, "Do you think it's the light that's attracting them?"
