Kanye West and Ellen Kanye West and Ellen

8 pm/ET Nickelodeon
Carly's school (yes, school — the iCarly gang are still hitting the books this summer) has a contest in which the prize is the school's best locker. And the lucky winner is Sam! And...Freddie. They both win, which means they have to share the premium locker. This, of course, gives the normally bickering buddies one more thing to squabble about. Meanwhile, Carly wants art lessons, and who better to teach her than her brother, the artist? — Jennifer Sankowski

Ellen's Bigger, Longer and Wider Show
9 pm/ET TBS
Ellen DeGeneres blows into the Windy City, taking the Chicago Theatre by gale-force storm with a retro variety show that features a breezy mix of eclectic specialty acts, dancers and music entertainers, including rapper Kanye West, magician David Blaine and guest DJ Nick Cannon. An installment of the 2009 Just for Laughs comedy festival, the special is DeGeneres' third variety-show edition. — Dean Maurer

Samantha Brown: Passport to Great Weekends
10 pm/ET Travel
The warm summer months may be upon us, but tonight the host is checking out the winter playground of Park City, Utah. Armchair travelers will delight in watching Sam soak in the area's natural scenery with former Olympians. And movie buffs will appreciate her insider's look at the famed Sundance Film Festival. — Karen Andzejewicz

10 pm/ET VH1
ZZ Top celebrates 40 years together with the same lineup in this intimate concert. Fans also get some inside dirt: The guys tell how "La Grange" is about the real-life "Best Little Whorehouse in Texas," talk about how the band and crew decided to take a homeless man's advice about their "Sharp Dressed Man" video shoot, and describe touring as Janis Joplin's opening act. Dusty Hill even does his Walter Brennan imitation. All that, and they play hits like "Tush" and "Gimme All Your Lovin'," too. — Fred Mitchell

Groomer Has It
9 pm/ET Animal Planet
The winner of this dramatic dog-grooming competition is chosen after a final challenge involving rare and exotic breeds. It's a nerve-wracking, nail-biting and ultimately triumphant night for either Lisa or Huber. Before we find out who will wear the crown, a recap show airing at 8 pm/ET gives fans a chance to relive some of the season's memorable moments with hosts Jai and Nemo. — Rhoda Charles
