The ATP stars in town for the Rogers Cup in Toronto were tasked with a fairly straightforward quiz. Titled "Canadian or American?" players were asked to raise a flag as answers to each question. 

Kevin Anderson, Denis Shapovalov, Milos Raonic, Grigor Dimitrov and Alexander Zverev all took part. They were great sports, as some of the questions were painfully obvious, and Raonic looked a little bored.

The best moments had to be surrounding the singer questions. All of the men knew where Justin Bieber was from, with Shapovalov adding a little "unfortunately" to his answer. The Canadian teenager was also part of a Celine Dion scandal. When Shapovalov gets it wrong (she's Canadian), a producer in the background appears outraged. "If you're going to say Celine Dion is American, you'll never show up in Montreal again."
