PRIME MINISTER'S QUESTION TIME (C-SPAN, SUNDAYS, 9-9:30 PM)

Imagine being the uncomfortable witness to another family's squabbling — a big, self-important, arch British family at that — and you've got this nearly 300-year-old parliamentary ritual in which adversarial MPs and the PM (currently Tony Blair) turn the House of Commons into a rhetorical snake pit. Unlike the bloodless, nasal drone of Capitol Hill, the verbal parrying in Prime Minister's Question Time is rancorous and snarky to the max, invariably inciting a most un-British cacophony of moans and harrumphs. "I think the attraction is the lack of decorum," says C-SPAN programming VP Terry Murphy. "Our Congress is so gentlemanly and matter-of-fact. There, it looks like they're having good fun."

RELIABLE SOURCES (CNN, SUNDAYS, 10:30-11 AM)

Who watches the watchdogs? These guys do. A lively roundtable discussion of how the media covered the week's news, Sources benefits from the wise guidance of host Bernard Kalb (who's been on both sides of the podium as a CBS reporter and a State Department spokesman) and the evenhanded analysis of Washington Post media critic Howard Kurtz. The show — unafraid to bite the hand that satellite-feeds it — recently examined whether CNN was compromising its ethics by letting Larry King do a "Got Milk?" ad. Quips Kalb, "Ted Turner has never called to say, 'You guys were too soft on us.'"

UNBRIDLED LUST AND NEARLY NAKED WOMEN!

CALIENTE (UNIVISION, SATURDAYS, 3-3:30 PM)

It's no mean feat to be both more provocative and more wholesome than MTV's The Grind, but Caliente does just that, week after sizzling week. The Hispanic feast of movable flesh is taped alfresco in various sun-soaked locales and — like its crass north-of-the-border cousin — is populated with writhing, barely clad bods kicking it to chart-topping lip-synchs and videos. (Although the dance tracks are Spanish-language disco hits, at least you know you'll probably be spared the Spice Girls.) If The Grind suggests a nightclub full of vacuous, self-conscious vamps with fake IDs, this is more of a truant summer-school class at an impromptu pool party. Think of yourself as the next-door neighbor peeking through the curtains. !Ay, ay, ay!

LOVELINE (MTV, WEEKNIGHTS, 11:30 PM-12:30 AM; SATURDAYS AND SUNDAYS, 11 PM-MIDNIGHT)

Man, does this show earn its TV-14 rating. Penises. Boobs. Orgasms. Boners. More penises. But thankfully for the FCC, Loveline is all talk. The setup: Our hosts — earnest physician Dr. Drew and loudmouth fratlike comic Adam Carolla — answer extremely explicit questions from twentysomething callers (Is Jell-O sex a health hazard?). Meanwhile, celeb guests contribute their own deep thoughts ("There's nothing wrong with being gay," Baywatch's Traci Bingham says to one freaked-out 22-year-old). The hour-long former radio show is a hypnotic — if somewhat disquieting — peek into the hormonal activities of the Lollapalooza set. Says Carolla, "I'm amazed what people don't know about rudimentary biology."
