It's a week of the weird: MPT showcases odd buildings along America's byways, and ABC spotlights 50 years of bloopers.

On cable, two programs -- USA's "The 4400" and Sci Fi's "They Are Among Us" -- investigate the mysterious. VH1's "I Love the '90s" brings back the not-too-distant memories of Ross Perot and Tonya Harding. On ABC, "Weddings" follows a nuptial extravaganza that unites two cultures. And Animal Planet's "Growing Up" series looks at baby animals and their human caretakers.

a program about unusual buildings

& other roadside stuff

Sunday at 8 p.m. on MPT

The name says almost all of it: This program offers a glimpse at the oddities that dot America's offbeat byways.

An enormous old water tower is the world's Largest Catsup Bottle in Collinsville, Ill. A Kentucky drugstore is actually shaped like a giant mortar and pestle. And a five-story, open-mouthed "Big Muskie" houses the National Freshwater Fishing Hall of Fame and Museum in Hayward, Wis.

Producer/narrator Rick Sebak also focuses on the people who take care of such places, which Sebak likens to both landmarks and national treasures. Who could argue, when the collection includes such gems as the Shoe House, the Corn Palace, and of course, the Big Duck, a snowy white duck-shaped structure in Long Island, originally built in the 1930s to sell -- what else? -- duck eggs.

The great domestic showdown

Sunday at 9 p.m. on ABC

Martha Stewart's domestic diva title may be temporarily tarnished, but this two-hour competition -- originally scheduled to air in May -- showcases those who believe their homemaking skills will outshine all the rest.

The contestants will face challenges in cooking, decorating, entertaining and event planning -- which is handy, since some of them work as event planners in real life. To increase the tension, all challenges will be timed.

The winner's reward is an appearance on "Good Morning America," a book deal and a pilot for a TV show of his or her very own.

Summer of Mystery! A thief of time

Sunday at 9 p.m. on PBS

PBS's yearly summertime mystery tour opens with an adaptation of one of Tony Hillerman's Native American police novels.

The film, like the book series, features New Mexico detectives Joe Leaphorn and Jim Chee, played by Wes Studi and Adam Beach. They face a baffling case involving illegal archeological excavation and murder.

Peter Fonda guest stars as an unscrupulous politician and rancher. Graham Greene portrays an evangelist who accepts stolen clay pots as prayer offerings.

Robert Redford is the executive producer of the film, which airs again at 10 p.m. on Wednesday.

MLB all-star game

Tuesday at 8 p.m. on Fox

Airing live from Houston's Minute Maid Park, the annual summer rite showcases the best of both leagues in their 75th meeting. The game's outcome now counts for more than bragging rights: The winning league gets home-field advantage during the World Series.

p.o.v.: thirst

Tuesday at 11 p.m. on WETA

A new documentary in this PBS series zeroes in on the way water is used, stored and valued. The program explores how pollution and population growth are turning the planet's dwindling water supply into "blue gold," or the oil of the 21st century.

Corporate water takeovers in California, India and Bolivia show what the "water wars" are about, as communities resist losing public control of their precious natural resource.

CMA Music festival:

country Music's biggest party

Wednesday at 9 p.m. on CBS

Taped in Nashville June 10-13, this festival draws country music fans who hope to hear, encounter and maybe even pose for a photo with their favorite singers.

Among those scheduled to perform are Brooks & Dunn, Dierks Bentley, Terri Clark, Pat Green, Martina McBride, Montgomery Gentry, Brad Paisley, Rascal Flatts, LeAnn Rimes, Uncle Kracker, Keith Urban and Hank Williams Jr.

aBC's 50th anniversary

blooper celebration

Saturday at 10 p.m. on ABC

Celebrating one's golden anniversary with blunders may not catch on in the real world, but for a television network, why not? Outtakes from comedies past show that sometimes the funniest material never made it onto the air.
