The woman has a dick

Listen up, nimrod. This "joke" is based on the premise of shock value, saying a woman has a penis when you are supposed to think of women as people without penises. Then the author roasts the reader by stating the woman in question is the reader's mother, followed by a threat to Jhon in New York City because the author is not smart enough to know that New York City is a big place, full of bodyguards.
