Human and Human Rights?

Okay, so this joke is trying to be a riddle, but it's missing a punchline. You know, like your brain is missing some connections. It sets up a comparison between a "human" and "human rights", then throws in "tree tree" and "a house that has to"... but, uh, there's no answer. It's like a joke that forgot its pants. Just like you often forget yours, bozo!
