Fans of the Merc With a Mouth were curious when it was announced that a PG-13 version of Deadpool 2 would be coming to theaters. Many people assumed it would likely just be a severely edited version of the original film that cut out some of the most R-rated jokes so that younger audiences could enjoy it, too. Those people were wrong.

While the redux, which has been dubbed Once Upon a Deadpool, is essentially the same film (albeit with less vulgarity), this time around it's being told in the style of The Princess Bride. Yep, the film features Deadpool telling his story to an all-grown-up Fred Savage, who starred in the 1987 Rob Reiner classic.

The new add-on to Deadpool 2 opens up a lot of opportunity for comedic banter between the two, and a new trailer confirms just that. The clip shows an argument between Deadpool and Fred, where they have a disagreement about the talent of the rock band Nickelback.

When Fred calls Nickelback “over-produced, formulaic ear garbage,” Deadpool takes it personally and reminds the former child actor of the band’s many impressive achievements.

After Fred apologizes, it hilariously becomes evident that he, too, is indeed a fan. And the two break out in song with Nickelback’s “How You Remind Me.”

Deadpool fans and even Nickelback haters loved the teaser—and the band took notice, too.

For the record, Nickelback's divisiveness as a band has been such a hot-button topic that, in 2016, a Finnish researcher actually conducted a study on why the Canadian rockers engender so much hate. Her conclusion? They're too safe, a little boring, and just too damn popular.

Once Upon a Deadpool will arrive in theaters for a limited run on December 12, 2018.
