Hey there, did you hear the one about the mathematician and the farmer? The mathematician says to the farmer, "I bet I can guess how many chickens you have in that coop over there." The farmer asks how, and the mathematician replies, "Well, if we add their legs together and divide by two, we'll have the number of chickens!" The farmer raises an eyebrow and says, "Interesting theory, but I already know how many chickens I have."

Indeed, the mathematician's method sounds clever, but it seems the farmer has his own methods for counting chickens!
