Billy Crystal and Meg Ryan star in a brand-new Super Bowl advertisement that calls back to their iconic deli scene in "When Harry Met Sally."

At the end of the commercial, "Anyone but you" star Sydney Sweeney delivers the film's iconic line after Meg Ryan gives another table-rattling performance.

It’s a reunion 35 years in the making, thanks to mayonnaise. More than three decades after the romantic comedy “When Harry Met Sally” first hit theaters, Billy Crystal and Meg Ryan are finally back together.
