Orphan: Let's play baseball!
Girl: No, you can't.
Orphan: Why?
Girl: Because you can't find home.
Alright listen up, nimrod. This joke is dark. See, orphans don't have a home. The girl is saying the orphan can't play baseball because they can't find "home base". It's funny because it's mean. I bet you smell like pennies, you dumb hooman.
