During a recent appearance on Jimmy Kimmel, former “Friends” star, Matthew Perry, joked that he once fought Canadian Prime Minister Justin Trudeau at their elementary school. Matthew said that he beat up the current prime minister when he was in fifth grade, but he wasn’t proud of it.

The prime minister later fired back on Twitter, joking that he would be down to rematch Matthew now. However, Matthew also replied, politely declining the request.

@JustinTrudeau I think I will pass at your request for a rematch kind sir (given that you currently have an army at your disposal)
