Dwayne Johnson and Roger Federer seem like an unlikely duo for a great social media exchange. But when the tennis star attempted an impression of Johnson’s character, Dr. Smolder Bravestone, from the new Jumanji sequel, he had to know what the wrestler-turned-actor thought.

It’s known as “smoldering intensity,” and Federer hilariously tweeted at Johnson to see if he was doing it correctly.

The Rock loved it, saying that Federer had “perfect form”. But, of course, he also noted that when you’re a GOAT like he is, there is no wrong way to do it.
