The Phoebe teaching Joey meme stems from the 2004 Friends episode 'The One Where Joey Speaks French.' In the scene, Phoebe attempts to help Joey learn French lines for an audition by breaking them down into small, manageable syllables. While Joey mimics each individual sound perfectly, he fails hilariously when asked to put the full sentence together, instead shouting rhythmic gibberish like 'Me poo poo.' This format became a viral sensation as a way to mock people who understand individual facts but fail to reach the logical conclusion, or for situations where a clear explanation is met with total misunderstanding.
