"Brewster" joke
There was a farmer who was in the fertilized egg business. He had several hundred young layers, called pullets, and 8 or 10 roosters whose job was to fertilize the eggs. He kept records and any rooster or pullet that didn't perform well went into the pot and was replaced. Now this took an awful lot of time. So when the farmer saw a set of 8 tiny bells that each rang a different tone he promptly bought them.
He glued a piece of foam rubber to each clapper shaft so the bell wouldn't ring except when violently shaken. He hung a bell on each rooster's neck and went and mixed a Mint Julep. Now he could sit on the porch and sip while filling out an efficiency report on the roosters by listening to the different tones of the bells and marking down each encounter.
The farmer's favorite rooster was old Brewster. Brewster was a fine specimen, but his bell didn't ring all morning. He went to investigate.
Several roosters were chasing pullets, bells a-ringing. Brewster had his bell in his beak so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Chagrined at first, the Farmer was soon so proud of Brewster he entered him in the county fair.
Brewster was an overnight sensation. They not only awarded him the No Bell prize but also the Pullet Surprise.
