TONIGHT'S MIGHT-SEE

"Greatest American Dog" finale, 7 p.m., CBS. We're down to the final three now. The winner gets $250,000 and fame. Or, at least, fame in doggy-TV circles.

OF NOTE

"America's Got Talent," 7-9 p.m., NBC. Ten more acts perform. On Thursday, we learn which of the final 20 are out.

"Bones," 7 p.m., Fox. The show got off to a dandy start last week with its London mysteries. Now it's back to the U.S. The victim is a TV host who revealed affairs, so the suspect list is enormous. Also, the socially awkward Brennan finds herself dating two guys.

" 'Til Death" season opener, 8 p.m., Fox. Joy has always flirted her way out of traffic tickets. When that fails, she begins a midlife scramble to the lingerie shop and plastic surgeon in a broad, moderately funny episode.

"Do Not Disturb" debut, 8:30 p.m., Fox. This comedy tries hard. It has a big hotel setting and a large, talented cast. Jerry O'Connell plays the lusty manager and Niecy Nash is his sharp-tongued human-resources director. The episode we saw (not the one that airs tonight) had an adequate amount of fun moments.

"Debating Our Destiny II," 10 p.m., PBS. Jim Lehrer, who has moderated 10 presidential debates, hosts this follow-up, focusing on the 2000 and 2004 debates.

"Sons of Anarchy," 7 p.m., FX. After barely eluding disaster last week, this motorcycle gang faces fresh probes. As the voice of moderation, Jax suggests an elaborate grave-robbing scheme. There are some nasty moments here, semi-balanced by deep characters.
