New TLC Special MY COLLECTION OBSESSION Premieres Sunday, August 21 at 10 PM ET

MY COLLECTION OBSESSION takes you deep inside the world of four of the country's most obsessed collectors -- each taking their material obsession to jaw-dropping extremes. The time they have spent searching, cleaning and maintaining their massive horde is only equaled to the thousands of dollars spent to acquire and display their prized possessions.

Darlene takes her love of shoes to a shocking extreme with over 15,000 shoe-related items. But will she take her shoe mania to new level? Kyle has been obsessed with his vacuum cleaner collection for ten years, but the biggest surprise about Kyle is that he is only 16-years-old! We join him on his hunt to acquire the ultimate addition to his prized collection. Marilyn has an impressive doll collection and even treats them as if they part of the family; washing, dressing and sometimes taking them to the playground. Harrell and Patrick's three-floor home is filled from floor to ceiling with memorabilia of the Queen of Country, Dolly Parton. But little do they know, their obsession is about to get them the surprise of their life!
