On TV this weekend
Nat Geo Amazing!, 7 p.m., NatGeo Besides the terracotta warriors of China, we get to meet scientists who trigger avalanches on purpose to study the effects. That's way cooler than another reality show about lumberjacks.
SEASON FINALE Wife Swap, 8 p.m., ABC Another season of substituting one head case for another comes to a close. Just in time for election season!
The Pillars of the Earth, 10 p.m., Starz William decides to attack Kingsbridge to thwart Aliena's success. Hey, we thought it was Jack and Alfred who were the ones really upset over her.
VISA championships, 8 p.m., NBC The five-day gymnastics championship that's not the Olympics comes to a close. This is when all the girls actively hate each other, not passively like they do when they're on a team together.
Class, 9 p.m., Hallmark Eric Roberts plays the dad to a snobby law student who ends up seeing how the other half lives by representing a single mom. By "other half" we mean the other 97 percent of Americans who don't make a quarter-mil a year or more. So what's the big revelation here, ya snooty jerk?
SERIES PREMIERE The Great Food Truck Race, 10 p.m., Food It's not enough that you can go get fast food anywhere — now fast food comes to you, as seven lunch trucks vie to win bragging rights. Outside of major metros with lots of foot traffic, if your truck can still afford to operate after this series, you can pretty much call yourself the winner.
SEASON FINALE Scoundrels, 9 p.m., ABC Wolf is angry that Cheryl is cheating on him. Girls who dig criminals just don't have any standards.
SEASON FINALE Kourtney & Khloe Take Miami, 10 p.m., E! All right, fine, okay, we know your daddy issues are ruining your lives and making your personal relationships impossible to maintain. Will you just take Miami and go already?
Comedy Central Roast of David Hasselhoff, 10 p.m., Comedy Central They've been advertising this one for a good two months, so tune in and see Hulk Hogan wearing a t-shirt with an arrow pointing to his crotch and "Suck it Hoff" in red block letters.
