On Wednesday, the 64-year-old actor paid a visit toThe Tonight Show Starring Jimmy Fallon, where he taught hostJimmy Fallonto do one of the iconic dance moves from the 1978 film’s finale.

The move? The four corners, a simple hip-trust Travolta and Newton-John, 69, did as their characters — Danny and Sandy — celebrated their romance at the school carnival.

Turns out, it was Travolta’s idea to do the move to begin with.

“Like withPulp Fiction,I grew up with all these kind of novelty dances,” he explained. “WithGrease, they needed a step for ‘You’re the One that I Want’ at the end. So I said, ‘We used to do the four corners, why don’t we do that?’ And the choreographer was like, ‘Show it to me,’ and I did.”

If Travolta is feeling reminiscent aboutGreaseit’s because it is the 40th anniversary of the hit movie musical.

Earlier this year,Newton-John revealed that she managed to salvage the skintight black satin pants she wore for “You’re the One That I Want”even though she had to be sewn in and out of them multiple times!

Despite everything the pants have been through, Newton-John still has them in her closet — but not for much longer! “I have them and I’m going to auction them off for my hospital this year,” the actress explained.
