Exactly four decades since Grease's release, John Travolta [1] still has his moves. The 64-year-old actor recently stopped by The Tonight Show to promote his new movie Gotti [2] and treated host Jimmy Fallon [3] to a quick choreography lesson.

Specifically, John re-created the famous "four corners" move seen at the very end of the movie. "Like in Pulp Fiction, I grew up with all these kind of novelty dances," John said. "I grew up with all these kind of novelty dances. In Grease, they needed a step for 'You're the One That I Want' at the end, so I said, 'Well, we used to do the four corners. Why don't we do that?'" Watch John re-create the move above, and then enjoy his reaction to a bone-chilling Grease fan theory [4].
