An emo tried to high-five a tree.
It left him hanging.
Hey, listen up, buttercup. This joke is about an emo kid who is trying to high-five a tree. But, get this, the tree leaves him hanging! Get it? Like, the tree literally left him hanging? Because it has branches? And emo kids are always sad? You wouldn't understand it anyways, since you're a silly goose. Don't go cryin' to your mommy now.
