A Central New York couple surprised their wedding guests with a "Beetlejuice" flash mob-like performance over Halloween weekend.

Nick Streeter and Allison Roy, of Auburn, N.Y., tied the knot on Saturday after six years of dating. After saying "I do," a strange but familiar song started playing during the best man's speech: "The Banana Boat Song (Day-O)" by Harry Belafonte.

Allison Streeter, 33, started lip-syncing the lyrics, as if she were possessed -- much like Catherine O'Hara's character Delia Deetz in the 1988 movie directed by Tim Burton and starring Michael Keaton. Guests laughed as the groom feigned confusion, but by the time the first verse began, both were standing together and dancing along.

Family and friends quickly joined in on the fun, waving black napkins and swaying to the music like in the famous dinner scene. The best man even tapped a bucket like Glenn Shadix's character Otho as every move was recreated perfectly, even screaming for the finale.

"We love 'Beetlejuice,'" Nick, 29, explained. "That's her favorite movie of all time. We had this idea, like yeah, we could do that for our wedding. We never took it too seriously until our DJ took it and ran with it."

Nick and Allison Streeter, of Auburn, N.Y., performed the "Day-O" dance from "Beetlejuice" at their wedding on Saturday, Oct. 29, 2016 at the Arrowhead Lodge in Brewerton, N.Y.

Jason Paussa, owner of Syracuse DJ company Salt City Sound Machine, said he thought it would be fun to do a scene from a popular and nostalgic movie like "Beetlejuice."

"You see wedding flash mobs, choreographed dances, or dance fake-outs all the time, especially someone in my position. It was only a matter of time before someone incorporated something from movies or TV," he explained. "You see a bride and groom do the ['(I've Had the) Time of My Life'] dance from 'Dirty Dancing' for their first dance, or a group of groomsmen do the dance to OK Go's 'A Million Ways.'"

Paussa made a tutorial video for "Day-O" and shared it with the couple the week of the wedding. Several guests also learned it while most were kept in the dark, but they didn't actually get to rehearse it together until the cocktail hour after the wedding ceremony.

"Everyone involved did an excellent job learning it in such a short amount of time and especially because we didn't have time until an hour or so before it happened to rehearse it in person," Paussa said. "We are all really happy the way it turned out. And honestly, it could not have turned out the way it did without Nick and Allison being so cool about it."

Nick and Allison Streeter have won several Halloween costume contests with their "Beetlejuice" outfits.

Nick Streeter, a disc jockey himself at Singers karaoke bar, said the wedding was just the latest in a series of "Beetlejuice"-themed memories. He told syracuse.com he and Allison won several Halloween costume contests with "Beetlejuice" masks that resemble Alec Baldwin and Geena Davis' characters in the movie.

They also got engaged while on a trip to Vermont, when they visited the town where the movie was filmed in East Corinth.

"The school and hardware store are still there," he said.

"Beetlejuice," also starring Winona Ryder and Jeffrey Jones, follows a recently deceased couple (Baldwin, Davis) who tries to scare the new owners of their house away with help from a supernatural troublemaker named Betelgeuse. Burton, Keaton and Ryder have all expressed interest in doing a sequel in recent years, but a rep for the filmmaker said earlier this year that there are currently no plans for "Beetlejuice 2."
