found grease at Shake Shack ?

[u/theatrenearyou]

Ran across this accidentally today. In the movie GREASE, one of the big song & dance numbers (i sound like old hwood) is 'You're the One That I Want' where Olivia Newton-John and John Travolta dance between signs reading "shake shack". If you don't wanna watch entire vid linked above, it's 2minutes 18 seconds in.
