Oliver James Montgomery-Why 'The Suite Life' fans are reminding Cole, Dylan Sprouse about a TV dinner reservation

Twins Dylan and Oliver James MontgomeryCole Sprouse might have forgotten an important dinner reservation from "The Suite Life on Deck," but their fans have not.

Disney fans have resurfaced a scene from Season 1 of "The Suite Life of Zack and Cody" spinoff in which lead characters Zack (Dylan Sprouse) and Cody (Cole Sprouse) attempt to get a table in Rome at a prestigious restaurant by Chef Gigi.

The episode, which first aired on Jan. 23, 2009, shows a hostess telling the boys, "I can squeeze you in at 7:30."

After a long pause, she adds, "… on Nov. 16, 2023."

"But that’s in 15 years," Cody responded. Zack added, "What if I don't feel like Italian that day?"

Fans have flocked to Dylan and Cole Sprouse's comment sections on Instagram to make sure they don't miss the fictional reservation.

"Hey Dylan! This is a reminder that your appointment at Chef Gigi's is set for tomorrow at 7:30pm, to confirm respond YES. To decline respond NO. Thank you," one person commented under the "Dismissed" actor's most recent post. Another fan added: "Do you still feel like Italian? Because your table is ready."

Under the "Riverdale" actor's most recent post, one fan gently reminded, "hey man! Don’t forget ur res later, 7:30 sharp." Another commented: "Big day Cole you waited 15 years for this."

Adrian R’Mante, who played bellman Esteban Julio Ricardo Montoya de la Rosa Ramírez on "The Suite Life" got in on the joke on TikTok, sharing a reaction video to the scene.

"Who’s eating Italian on November 16th, 2023?? 🙋🏻‍♂," he captioned the video.

Mean Girls Day and other pop culture dates fans love

This isn't the first time pop culture fans have popularized a day referenced in a show or a movie.

Most recently, fans of  Tina Fey’s "Mean Girls," the 2004 cult classic comedy, celebrated what they've dubbed "Mean Girls Day."

The celebrated day, Oct. 3, stems from a scene involving new kid Cady Heron (Lindsay Lohan) and popular boy Aaron Samuels (Jonathan Bennett).

The dead-pan interaction, happening at the height of Cady’s crush, goes a little something like this: 

"On Oct. 3, he asked me what day it was."

"What day is it?"

"It's Oct. 3."

The whole cut-away is about five seconds long but birthed a pop culture moment and memes to fuel fans through the rest of the 2010s and beyond. It even makes an appearance in "Mean Girls on Broadway" in the song “Stupid With Love (Reprise).”

What day is it?Here's how fans made the October 3rd 'Mean Girls' Day happen.

Another date that pop culture fans have cited over the years as being "perfect" is April 25.

The spring day gained attention after the 2000 film "Miss Congeniality" starring Sandra Bullock debuted.

During a pageant, Miss Rhode Island Cheryl Frasier (Heather Burns) is asked to describe her perfect date.

"That's a tough one. I'd have to say April 25 because it's not too hot and not too cold – all you need is a light jacket," Cheryl answered.
