Orphan Baseball

Listen up, nimrod. This joke is funny because it uses the word "home" in two ways. First, "home" is where you live and orphans don't have parents, so they do not have a place called "home". Second, "home" is the last base you run to in baseball to score a point. The joke is an example of a pun, which are words that sound alike, but have different meanings. This is a low brow joke, just like you.
