By now, most people have probably heard of TLC's hot new series "My Strange Addiction." It features people who confess to doing bizarre things such as being sexually attracted to a motor vehicle, eating cat food and having an unusual relationship with a baby doll head.

These tales are so strange, who could make them up?

Sunday night's episode may be the grossest yet. Carrie, 53, has been addicted to drinking her urine for four years. She drinks about 80 ounces every day.

There's more. Carrie brushes her teeth with her urine, uses it as lotion and sucks it up her nostrils. The woman even believes it treats her cancer despite no medical proof that it works.

Why do these people go on national television to talk about their disturbing addictions? Are they trying to help others who may have similar issues? Are they looking for their 15 minutes of fame?

The season finale airs this Sunday, March 18, at 10/9c.
