Little boy: I know three things about aliens. One, they don’t have hair. Two, they don’t have mouths. Three, they don’t have privates.
20‐something: Then how do you know if it’s a boy or a girl alien?
Little boy: Um, they’re not boys or girls. They’re its… Or she‐males.
20‐something: Where did you learn ‘she‐males’ from?!
Little boy: Third Avenue.
