Porcupine Difference
“What’s the difference between the North American porcupine and the African porcupine?” the society matron asked the zookeeper.
“The principal difference is the North American species has a longer prick.”
This, as you might suspect, distressed the prim and proper matron who stormed immediately to the zoo manager’s office to protest.
The zoo manager said, “Ma’am, I do apologize for my staff’s uncouth choice of terms. What the keeper should have said is that the North American species has a long ‘quill.’
In fact, their pricks are just about the same size.”
