“Billy Crystal-core” is dominating the internet as fashionistas aim to emulate the cozy style of the rom-com star in the 1989 Nora Ephron smash, “ When Harry Met Sally .” In that film, the funnyman, now aged 76, plays a political consultant who famously rocks a chunky white fisherman knit sweater.

Coinciding with the 35th anniversary of their beloved movie, Crystal and Ryan returned to the famed Katz’s Deli in New York City to recreate one of the film’s most famous scenes, where the floors were still greasy, the commotion was still loud, and, well, the orgasms were still very fake.

The two actors revisit an iconic scene from their legendary romantic comedy in the commercial, a nostalgia play titled “When Sally Met Hellmann’s” (watch below). Ryan and Crystal play friends whose connection turns romantic in the 1989 movie written by Nora Ephron and directed by Rob Reiner.
