Please tell me about 'Knock knock Joke', if possible. I was told 'knock knock joke' by one of my language partners. But unfortunately, I couldn't understand the meaning. Afterwards, I searched about mead because it is not familiar for us Japanese. And I learned about the origin of the word of Honeymoon. Perhaps that joke is something to do with Honeymoon, I guess. But I still can't guess what does it mean. That's why I tried to ask on here about that joke. Please tell me about 'Knock knock Joke' like below, if possible. J: knock knock Y: who's there? J:honey bee Y: honey bee who? J: honey bee a dear and get me a soda
