ATP stars Stan Wawrinka, Milos Raonic, Dominic Thiem, Steve Johnson, Tomas Berdych and Bob and Mike Bryan took part in a heated Jenga competition. With every successful block removed, each player had to answer the question engraved on it. While most of the answers were expected (best serve: John Isner), a few were surprising.

Case in point, Raonic's go-to karaoke song is "Don't Stop Me Now" by Queen. I bet his fans would pay a lot of money to witness such a performance.

Viewers also learn that Thiem's cheat food is cheeseburgers (classic) and the last concert he attended was Shakira (his hips don't lie.)

Spoiler: The Jenga champions in the end are Wawrinka and the Bryans.
