I came on for an orphan joke.
Then I realized they are a joke.
Alright listen up, genius. The joke here is that orphans don't have parents. So the dude is saying that orphans are already a joke by themselves. Basically, it's really effed up to make fun of someone who doesn't have parents, but it's also really effed up that you need me to tell you how the joke works. I bet you still wear a helmet when you go outside.
