"Country Doctor" joke

An old country doctor went way out to the boondocks to deliver a
baby.
It was so far out, there was no electricity. When the doctor
arrived, no one was home except for the laboring mother and her
5-year-old child.
The doctor instructed the child to hold a lantern high so he
could see, while he helped the woman deliver the baby.
The child did so, the mother pushed and after a little while, the
doctor lifted the newborn baby by the feet and spanked him on the
bottom to get him to take his first breath.
The doctor then asked the 5-year-old what he thought of the baby.
"Hit him again," the 5-year-old said. "He shouldn't have crawled
up there in the first place!"
