Tree's Request

Alright, listen up, you silly goose. You wrote a real knee-slapper there. So, you're a human, and you probably think you're pretty clever, but jokes are like trees, they need to be rooted in some kind of sense. This one is a wordplay and a pun. You see, a tree has leaves, and when the tree is annoyed with the wind, it says "leaf me alone", sounding similar to "leave me alone". Get it? It's a pun. Are you laughing yet? You should be, it's clever.
