If you've got a freeloading friend or relative you've dubbed a "leech," you may want to find another insult after watching this new episode. Its segment on real leeches is fascinating and covers their renaissance as medical tools -- to drain off excess blood from reattached appendages. Other segments look at new developments in stem-cell research and the search for life on other planets. There's also a profile of underwater explorer Edith Widder.

One of the better episodes from the show's 11th season, "Fantastic Easter Special" is a hilarious sendup of "The Da Vinci Code." Young Stan can't figure out what eggs and bunnies have to do with Easter. The answer lies with a secret society called -- wait for it -- the Hare Club for Men. The show also gets in a dig at Bill Donohue, the controversial Catholic anti-defamation activist who spoke out against an earlier episode.

Rubirosa (Alana De La Garza) is playing for the other team -- and we don't mean in the Seinfeldian sexual-orientation sense. The legal aid lawyers are on strike, so she's pressed into service as court-appointed counsel for a man (Brad William Henke) accused of murdering one of the strikers. It'll get interesting when she and Cutter (Linus Roache) face each other in court in "Strike."

Despite the public questioning of cast choices, this 2006 actioner was well-received by audiences. Daniel Craig stars as Agent 007, who gets his first assignment here. This version also explains Bond's cavalier attitude toward women. Judi Dench returns as M, with Eva Green, Mads Mikkelsen, Jeffrey Wright and Jesper Christensen also starring.

The cast rocks, but not enough to raise this 2006 Western above mediocrity. Salma Hayek and Penelope Cruz play two very different women in late 19th-century Mexico who team up to rob banks. Their motive: Buy out the greedy New Yorker (Dwight Yoakam) whose land grab cost both women's fathers their lives. Sam Shepard and Steve Zahn are among the other actors wasted on this improbable script.

Culture clashes are nothing unusual on this addictive series, but backwoods Kentucky wife Karen Sutton, who is used to pampering her husband, is in for a jolt when she trades places with Samantha Myers, a corporate Illinois mom who leaves all the domestic chores to her stay-at-home husband, Shane -- and whose kids are obsessed with hunting for ghosts.

It helps to be connected. In this episode, though, it's the diplomat who's glad she knows an FBI agent. Kate Jackson guest stars as Prentiss' (Paget Brewster) mom, an ambassador who seeks the Behavioral Analysis Unit's help in catching kidnappers. The victim, a Russian immigrant, is losing parts of his body with every ransom demand. The team soon discovers the Russian mob is involved, so this will be messy.

Even supernanny Jo Frost has her work cut out for her when she tries to bring order to the home of Lisa and Steve Daniels, who have let discipline deteriorate to the point that their six ill-behaved children indulge in spitting, cursing, hitting and other random misbehavior. Things come to a head when mom Lisa refuses to follow through on a "timeout" for one of the kids, precipitating a tense face-off with Jo.

A couple of years ago, he walked on water without benefit of divine intervention. But that was small potatoes; he traversed a mere pool. In the fourth-season premiere of his series, illusionist Angel ups the ante by attempting to traverse Lake Mead, the largest man-made lake in the United States. Expect more wild stunts as the season continues, including a live episode in which Angel tries to escape from a building that's about to implode.

Hey, kids, let's make a sequel to the worst movie ever to bear the once-proud "National Lampoon" label! Eek. If 2003's "Dorm Daze" was a train wreck, this horrid 2006 direct-to-video follow-up is a disaster of Titanic proportions -- literally, as it's got the collegiate characters doing the semester-at-sea thing. And it's got Kato Kaelin. As himself. 'Nuff said.

Boo! This Halloween episode was directed by Joe Dante of "Gremlins" fame, and it shares that movie's cheeky blend of scary and serious. Danny and Lindsay (Carmine Giovinazzo, Anna Belknap) investigate a family's murder at a house in -- wait for it -- Amityville. Yes, the same house where another family was slaughtered years earlier. Mac, Stella and Flack (Gary Sinise, Melina Kanakaredes, Eddie Cahill) investigate the death of a zombie. No, really.
