"In grade school in the 60s, we had only one male teacher. Except for the gym teachers. They had the weakling-terrifying names of Mr. Dick and Mr. Harold Garilla – yes, Hairy Gorilla – but you expected the phys-ed teachers to be barking testosto-bots. All the other teachers, except for fifth grade, were women."

Made-up citation: "I'm taking my testosto-bot back to Target. It took my lunch money, stole my wife, and provided a role model for my sons. That's unacceptable."
