Seventeen years after the final Friends episode, students and educators say that the show, still seen widely in syndication around the world, works well as a learning resource. The dad jeans and cordless telephones may look dated, but the plot twists — falling in love, starting a career and other seminal moments in a young person’s life — are still highly relatable. “It’s entertaining compared to other sitcoms, and it addresses universal issues,” Konus, 29, said. “The themes speak to everyone.” Over the years, several prominent celebrities have said that they learned English from Friends. The list includes Jürgen Klopp, the German soccer coach who helms Liverpool in the English Premier League; a number of Major League Baseball players whose first language is Spanish; and Kim Nam-joon, the leader of the South Korean pop group BTS.
