Going to the dogs Keeping in mind that it's unclear whether animals understand anything other than English, Cesar Millan will travel to Australia for part of the sixth season of "The Dog Whisperer" (8 p.m. today, National Geographic). Before that lengthy trip, the trainer adopts four pups and documents their progress over eight months.

Knock, knock Bill Bellamy is convinced that "Last Comic Standing" didn't pinpoint enough talent. That's the only way to explain the existence of "Bill Bellamy's Who's Got Jokes" (9 p.m. Saturday, TV One), in which celebrity judges evaluate stand-ups from across the country. Contestants who have actually seen more than two Bellamy movies get extra credit.

Family affairs Those worried about Hugh Hefner's love life can rest easy. In a new season of "The Girls Next Door" (9:30 p.m. Sunday, E!), the Playboy magnate squires three fresh beauties, including twins. Fans of the Original Three need not despair: Holly makes a guest appearance in the premiere. For those who find "Girls" too taxing and sophisticated, there's "Leave It to Lamas" (10 p.m. Sunday, E!), the series that dares to treat Lorenzo Lamas as a major Hollywood figure. The show's real star, however, is daughter Shayne Lamas, who's desperate to prove that she's the next Kim Kardashian. Who said today's young people aren't ambitious?

Dirty prancing When "Family Guy" (8 p.m. Sunday, KMSP, Ch. 9) misses, you hurt from wincing. When it scores, you hurt from laughing. Last month's season premiere, in which Brian and Stewie pop in and out of alternative universes, was an instant classic, while last week's outing, in which Lois finds out she has Jewish roots, left me cold. Tonight's offering could go either way, especially since it involves Peter's obsession with "Road House." Will the Patrick Swayze jokes be crass or clever?
