Honeydew
We are not really sure what the punchline at the end of the joke meant, but it does not really matter, this entire thing fell apart quickly. This person opened up the conversation with a knock-knock joke, but the recipient replied with ‘yoooo’. She clearly torpedoed the chance of the joke working right from the start.
Those types of jokes are risky if the person you are sending them to is not in the mood to play along. Make sure you test the waters out before you just message people your cheesy jokes. You may end up failing badly like this guy here and nobody wants that.
