FRIDAY, AUGUST 21
Jockeys (Season 2 premiere, 7 p.m., ANIMAL): These little guys have some big problems. One jockey is returning to the track after an injury, another is trying to make a name with an unknown horse -- and they're all vying for a spot in the Kentucky Derby.
The Soup (10 p.m., E!): Joel McHale has some particularly choice news and gossip to work with -- and make fun of -- this week, including Richard Hatch's slammer situation, Jon Gosselin's potential new moneymaker, and ex-Megan Wants a Millionaire contestant Ryan Jenkins.
SATURDAY, AUGUST 22
High School Musical and High School Musical 2 (7 p.m., DIS): All the recent hype over Glee has really made us miss Zac Efron. Actually, that's not true. We'd miss Zac Efron anyway.
SUNDAY, AUGUST 23
Homeland Security USA (3 p.m., ABC): This reality series explores the US border patrol -- and its battle against illegal immigration and drug smuggling. In this episode, ABC examines how dogs are trained to inspect trucks at the border and in mail-carrier depots.
Miss Universe Pageant (9 p.m., NBC): For those who like pretty girls in bikinis, the appeal of this pageant is obvious. And if you don't like watching pretty girls in bikinis, you can always just make fun of the stupid things they often say. There's bound to be at least one instance of backwards babbling -- guest performer Heidi Montag (Pratt? Montag-Pratt?) can add idiocy to any occasion.
Mad Men (10 p.m., AMC): The season premiere opened the proverbial floodgates -- and we're ready for a swim. We love Mad Men -- and we can't wait to see what happens when Don (Jon Hamm) dines with the uppity new British boss and Roger (John Slattery) starts planning his wedding.
