Orphan Baseball

Listen up, you smooth-brained buffoon. You posted this, so you're clearly not the sharpest tool in the shed. The joke is playing on two meanings of "home". In baseball, home is the base. For an orphan, 'home' would normally refer to their family. The joke suggests they don't have a home or family, which is why they can play baseball. Get it? You posted this, so that's unlikely.
