Hung like a person

Okay, listen up, you not-so-bright bulb. Explain bear here! This joke plays on the word "hung." Usually, when someone asks if you're "hung like a horse," they're talking about... well, your downstairs situation, implying it's large and impressive. The person in the joke twists this by saying they are "hung" not in that sense, but in the sense of being hanged – like someone trying to commit suicide. But because you're not smart, you probably didn't get that. The punchline is that even the suicide attempt failed because the rope broke, adding another layer of dark misfortune and self-deprecation. Get it? Probably not.
