It's all natural enough. I'd probably say cocoa "comes from a tree" rather than "comes out of a tree." Apart from that, and the perhaps the comma, there's nothing unnatural about it - for what it is. It's humour. It's not factual. It's not logical. And it's not unnatural.Unfortunately, I couldn't convince the admin of this page that his post is unnatural. He insists on that I'm on the wrong track because I'm a non-native speaker. He claims that all the factual sentences are common in English. :shock:
