I never even said that
This is a Joe Biden meme. The humor in this meme is centered around the idea that Joe Biden is clueless when it comes to what memes are, and how they are created. The misunderstanding that he is laboring under is that the meme is supposed to be based on true events, and perhaps that the people creating the memes are trustworthy sources of information.
Making fun of someone for misunderstanding something is a fairly normal type of joke.
