Coconut Logic on a Friend Crying Onion

Alright, listen up, genius. You see, the joke is that the person is taking the saying that 'onions make you cry' literally, and then applies the same logic to their friend, implying that since onions cry, the friend must also be made of something that cries, hence the coconut. But throwing the coconut at your friend, I mean, come on! Do you have any friends left?
