'My Crazy Obsession' Premiere: Couple Treats Their Favorite Cabbage Patch Kid Like A Son (VIDEO)

Joe and Pat Prosey love Cabbage Patch Kids. In fact, they love them so much that they've spent more than $1 million collecting and housing a whopping 5,000 of them.

On the series premiere of "My Crazy Obsession" (Wed., 10 p.m. EST on TLC) Joe and Pat took their favorite Kid, named Kevin, out to buy a gift for their real-life adult daughter -- a.k.a. "Kevin's real sister" -- Vicki.

Vicki lives in Los Angeles and does not share her parents' passion for all things Cabbage Patch. "I do not think of Kevin like a brother," she said.

As the Proseys shopped around for a suitable gift and asked Kevin what he'd like to buy Vicki, the store clerks had a hard time keeping a straight face.

Barely restraining her laughter, clerk Suzette Shaw said, "I was shocked when they wanted me to talk to the doll, 'cause I was about to bust out."

"My Crazy Obsession" continues on Wednesdays at 10 p.m. EST on TLC.
