Meet the Couple Who Collected 6,000 Cabbage Patch Kids: 'I Don't Care What Other People Think' (Exclusive)

Narrated by Neil Patrick Harris, the Cabbage Patch Kids-focused documentary 'Billion Dollar Babies' is in select theaters Friday

Joe and Pat Prosey are proud parents to thousands of Cabbage Patch Kids.

PEOPLE has an exclusive clip from the documentary Billion Dollar Babies which shows the Maryland-based couple discussing their sizable doll collection. The film, narrated by Neil Patrick Harris, tells "the unbelievable true story you never knew about the toy craze that started it all," according to a synopsis.

The Proseys say in the clip that, at one point, they had collected about 6,000 different Cabbage Patch Kids dolls ("no duplicates," says Pat), and even once opened a museum in Maryland "filled to the brim" to showcase them all.

Now, "There are 491 Kids in our bedroom," Pat says. "Every wall space has shelving, and it is filled with Cabbage Patch Kids."

"I specifically designed the bed myself," says Joe. "I came up with the idea of a bunk bed over a bed to get more Kids into the room, so they're all around us."

In the clip, Pat references the "Oath of Adoption" that comes with each doll, before her husband recites: "I promise, with all my heart, to give this special Cabbage Patch Kid all my love and affection, and in every way possible be the best adoptive parent in the whole world."

"I guess I was the father of the 6,000 Cabbage Patch Kids that we had," Joe adds.

"No, Xavier Roberts is the father of all Cabbage Patch Kids," Pat says with a laugh, referencing the creator whose work inspired the dolls.

"The Cabbage Patch Kids become a part of you, like Kevin here and Meg sitting there," Joe says in the clip, referring to the dolls sitting on their laps.

"I don't care what other people think about me," Pat says, laughing. "Most of the time, you know, you get what you see."

Billion Dollar Babies chronicles the Cabbage Patch Kids popularity that began around 1983, with director Andrew Jenks saying in a statement, "It was madness — a sustained, enduring frenzy that gripped much of the American public, more widespread, deep and lasting than any toy craze the United States had ever witnessed."

The documentary also covers legal woes — including a lawsuit from 1981 in which late doll-maker Martha Nelson Thomas claimed she'd "been ripped off," according to Jenks — featuring interviews with those close to Thomas, as well as Roberts himself, now 68.

"What I discovered during this journey was an unlikely tale about American entrepreneurism, consumerism, innovation and capitalism," the director said. "A tale about two American artists: one who found great fame and raked in millions of dollars, and another who died with little money and a largely unknown body of work."

The film "tells the story of how and why the Cabbage Patch Kids became an iconic doll, the ways in which they changed toy history and unravels, for the first time, who came up with the idea of the Kids who stole America’s heart," Jenks added.
