By the way, what do you mean by "playing the piano", "playing the piano" and "playing cotton" in World Cup jokes?

If you compare playing football to playing the piano-there are piano players and piano players in Argentina; Spain plays the piano, and no one lifts it; Everyone in Germany plays the piano, but no one plays it. A group of piano players came to England, but the piano didn't come.

Some people say that football is three people playing the piano and one person lifting the piano. According to my understanding, "playing the piano" means defending, and "playing the piano" means attacking.
