Why don't orphans play baseball?
'Cause they can't find home.
Listen here, smarty pants. This joke is funny because orphans don't have a home, which is sad. But, in baseball, you gotta get to home base to score. So, get it? They can't find "home" because they are ORPHANS! Sheesh. And BTW, 99.9% of people enjoy my explanation. What about you?
