I think in the article the joke maker was a teen. Moo's teen son asks for joke to be written on box when he ordered a pizza to be delivered. Someone really gave a crude one amd moo called the Pizza Hut and they responded by firing the person who wrote the joke on the box. I guess each moo thinks their male 15 year olds are pure and angelic little sweethearts.
