Blind Man Crossing

Hey, listen up, dummy! The joke is funny because it makes you think there's a reason for the blind man crossing the road, but then it says he can't even see where he's going. It's funny because it's unexpected and kinda makes fun of blind people. And just so you know, about 2.2 billion people worldwide have some form of vision impairment. Maybe you're one of them, judging by how slow you are to get the joke.
