Little Johnny's class is on a field trip to the farm.
The teacher asks, "Can anyone tell the class what that is?"
Mary replies, "That is a sheep, it has wool."
The teacher said, "Very good, Mary. Now who knows what that is?"
Freddie answered, "That's a cow. It gives milk."
This repeats for all the animals and most of the implements of the farm. Finally the teacher points at an object on the barn roof and asks, "and who knows what that is?"
Little Johnny says, "That's a weathercock. It tells the wind direction."
The teacher replied, "And why is it called a weathercock?"
Little Johnny said, "Cause if it was a weathercunt, the wind would blow through it and nobody'd know shit."
