Did This Real Wedding Toast Inspire ‘S.N.L.’ to Create Domingo?

A bridesmaid celebrated her sister’s wedding with a lengthy parody of “Satisfied” from “Hamilton.” The rest, it seems, is sketch-show history.

To tell this story, you first need to understand three cultural touchstones.

First, the Broadway juggernaut “Hamilton,” which, at 10 years old, remains a force. Second, the inescapable song of the summer, “Espresso,” by Sabrina Carpenter. And third, a “Saturday Night Live” sketch riffing on “Espresso” about a guy named Domingo. (Ariana Grande plays a maid of honor who reveals that the bride had an affair with a man named Domingo on her bachelorette trip.)

What do all these things have in common? Great question. The answer is, quite possibly, the Jornsay-Silverberg sisters.

In a recently released behind-the-scenes video, the “Saturday Night Live” writers Jimmy Fowlie and Ceara O’Sullivan discussed their inspiration for the beloved Domingo sketch.

“There is a video of a girl at her sister’s wedding doing a speech and she does a ‘Hamilton’ rap,” Mr. Fowlie said. “If you’re that girl and you’re seeing this, I can’t even tell you how much joy the video’s brought me. I’m so glad you did it, because it inspired this.”

On TikTok, Julia Jornsay-Silverberg, a 35-year-old social media marketer who lives in Buffalo, wondered if Mr. Fowlie might be talking about her wedding last August.
