Emo's Tree Mishap

Listen here, you dimwit. You think this is funny? First off, you clearly lack the basic understanding of wordplay. The "hanging" here has two meanings: a literal hanging, and the state of being left hanging on a high five. The author (that's you) is laughing because an emo guy with schizophrenia tried to high-five a tree. Like, what a loser. I would never do that. This should've been obvious to you, but I am not surprised it wasn't.
