"Strange" doesn't seem to adequately describe some of the addictive behaviors profiled on this series. "Dangerous," even "life-threatening," come much closer. Each half-hour episode features two adults who resort to extreme compulsions in an effort to soothe their emotional demons. Some of the addictions explored include sleeping with a turned-on blow dryer, eating bathroom cleanser, eating half a roll of toilet paper a day, extreme bodybuilding and thumb sucking.

"Extreme Cheapskates" profiles people who stop at nothing to spend nothing. From making reusable toilet paper and reusing dental floss to diving in garbage bins for gifts, these penny pinchers devise outrageous ways to cuts costs by any means necessary. In the half-hour episodes, viewers meet nifty-thrifty folks including Kay, who washes her clothes while she showers; Greg, who flushes his toilet just once a week; Ben, who makes his own toothpaste; Abdul, the "ultimate haggler"; and Vickie, a mother of five who refuses to spend money for a telephone, a television or even new clothes for her kids.

A look into the lives of people with food addictions.

Telling powerful stories in hourlong episodes, TLC follows medical journeys of morbidly obese people as they attempt to save their own lives. The featured individuals -- each weighing more than 600 pounds -- confront lifelong emotional and physical struggles as they make the courageous decision to undergo high-risk gastric bypass surgery. In addition to drastically changing their appearances, they hope to reclaim their independence, mend relationships with friends and family, and renew their feelings of self-worth.

The half-hour program provides viewers with in-depth reporting on one or more of the major stories in the news, with occasional segments on pop culture. Journalists Juju Chang and Byron Pitts share hosting duties for this late-night program.

The Johnstons -- all seven -- of Forsyth, Ga., are the subjects of this reality-documentary series. The brood, TLC says, are "the world's largest known family of achondroplasia dwarfs." Achondroplasia is a genetic disorder of bone growth, but the series demonstrates that size only matters in the amount of love the Johnstons provide. Trent, a grounds supervisor at a local college, and housewife Amber have two biological children -- Jonah and Elizabeth -- while Anna, Alex and Emma were adopted from Russia, Korea and China, respectively. Episodes deal with everything from high-drama soccer tryouts to a disastrous attempt at a "birds and bees" discussion, all framed by the family tackling a massive renovation of their 6,000-square-foot, circa 1891 home.

Long-distance relationships have challenges that are sometimes difficult to overcome but consider if the distance traveled was halfway around the world and a couple had just 90 days to decide whether the courtship should conclude with marriage. That's the situation facing the men and women profiled in this series, which shares the complexities of international romances. Using a visa that allows foreign fiancees of American citizens to travel to the U.S., the men and women experience life in the States with their prospective mates for the first time. Culture and language barriers must be overcome -- not to mention the stigma of being thought of as mail-order spouses -- but here's the elephant in the room: The couples must marry before the visas expire in 90 days, or else the visitors have to immediately return to their countries. With the clock ticking, these couples discover if their "happily ever after" is meant to be.

She conducts both private and group readings and deals with skeptics as well as believers. At home, husband Larry and kids Victoria and Larry accept the work she does, although they don't always love it. In the Caputo house, dad and kids think the spirits always come first, but for Theresa there is no escaping her gift.
