As addictions go, a 22-year-old woman named Keyshia has a doody, er, doozie.

She's addicted to the taste of dirty, pee-filled diapers, which she developed a taste for two years ago, according to an episode of "My Strange Addiction" airing Jan. 15 on TLC.

Since that first stained diaper, Keyshia estimates she slurped her way through 25,000 soiled nappies, which is enough for six babies' lifetimes.

In one scene during the show, her fiance Jerome gripes about how she leaves the diapers everywhere, including mugs.

"Just wash the cup" is her retort.

Her fiance is shocked by how far she will go for a taste.

"I've tried to work with her, but she goes beyond for her diapers," Jerome said. "She's even willing to dig in the garbage."

In the episode, Keyshia attempts to get the diaper-soiled monkey off her back.

But it's not easy.

"I'm going to smell them one last time then you can have them," she said.
