America's Got Talent
9 pm/ET NBC
Season 5 of the sunny summer series rolls on, as do the live performance showcases featuring disparate acts vying for top-talent honors and a cool $1 million prize. Last night, 12 more acts from the Top 48 took the stage, and now their offbeat skills will be rated in the season's second results installment. Four victorious acts will advance and join last week's winners in the longed-for Top 24. Meanwhile, the innovative theatrical collective Cirque du Soleil performs a routine from the show , and it's full steam ahead for the rock band Train when they deliver the song "Hey, Soul Sister." — Dean Maurer

Hot in Cleveland
10 pm/ET TV Land
This series was already trafficking in TV nostalgia with regulars Valerie Bertinelli, Betty White, Wendie Malick and Jane Leeves, and its list of guest stars, which so far includes Carl Reiner, John Schneider and Wayne Knight, has only added to its pedigree. Tonight the show, which was recently renewed for a 20-episode second season, continues its journey into yesteryear when Melanie's mother (Shirley Knight), Victoria's father (Hal Linden) and Joy's mother (Juliet Mills) all pay a visit on the same weekend. — Joe Friedrich

Pros vs. Joes
10 pm/ET Spike
In an unusual episode, former NBA champions Kenny Smith, Rick Fox and Hakeem Olajuwon take on three other pros on the hoops court. There is a catch, though: They face NFL stars Donovan McNabb, Antonio Gates and Terrell Owens. While you might think this should be a cakewalk, know that all three of the gridiron guys played college hoops — after the hoopsters had already played in the NBA. — Brendan Curley

Fabulous Beekman Boys
While it's hard to think about enjoying that big Thanksgiving dinner when our calendars say it's still July, it's even harder to imagine a situation in which your folks haven't met your significant other's folks in the decade-long span you've shared. In this episode, those unusual elements merge as the Beekman Boys do their own take on Guess Who's Coming to Dinner. — Michael Chant

American Masters
9 pm/ET PBS (check local listings)
"There's a feeling in my gut that says you haven't written that one song yet, the one that's gonna live forever," says Merle Haggard of what keeps him motivated, if not alive, 40-plus years into a career filled with just such timeless songs. This insightful profile features plenty of music, archival footage and interviews with Haggard, his family, and such friends as Kris Kristofferson and Tanya Tucker. If you're not a Haggard fan going in, you're all but guaranteed to be one going out. — Jeff Gemmill

Confessions: Animal Hoarding
Stories about animal hoarders sometimes make news, but rarely does the public get to view the specific challenges involved in treating those with the compulsion, nor its effects on their family and friends. In this documentary series, Animal Planet examines the psychology behind the obsessive need to acquire and house animals. The first episode profiles a man with 30 cats, and a woman who ignores life in unsanitary conditions and refuses to let her dogs go outside. Rhoda Charles

Meanwhile, a sexy celeb (Kelly Carlson) cozies up to Castle. — Rhoda Charles
