A small town Doctor was famous in the area for always catching really large fish.  

One day while he was on one of his frequent fishing trips he got a call that a woman at a neighboring farm was giving birth. He rushed to her aid and delivered a healthy baby boy.  

The farmer had nothing to weigh the baby with so the Doctor used his fishing scales.  

The baby weighed 22 lbs 10 oz.

 

(Think about it.)
