On TV this weekend
SEASON PREMIERE Shark Tank, 8 p.m., ABC You know the old saying: Build a better celebrity ghostwriting business or online funeral-planning service, and the world will beat a path to your door.
SERIES PREMIERE On Freddie Roach, 9:30 p.m., HBO Director Peter Berg (Friday Night Lights) takes a look at one of boxing's most celebrated trainers. This would be an amazing documentary series, if anyone in America still followed boxing.
Drew Peterson: Untouchable, 8 p.m., Lifetime Rob Lowe plays a sinister husband who may or may not have murdered his third and fourth wives, as opposed to a real-life sinister husband suspected of sexually harassing his kids' nanny. You'd think the first and second wives would've warned someone.
SERIES PREMIERE Bayou Billionaires, 9 p.m., CMT A Louisiana clan finds out their land contains a huge natural-gas deposit. Who needs The Beverly Hillbillies when you have this?
SEASON PREMIERE My Big Redneck Vacation, 9:30 p.m., CMT Tom Arnold hosts more rednecks leaving the country and hitting the road. We suspect the Bayou Billionaires will be on soon enough.
Desperate Housewives, 9 p.m., ABC We stopped watching this show when Lynette and Tom split, so now that we know she's dating Renee's hairdresser, we can only hope he's played by Rob Lowe from Drew Peterson: Untouchable.
SEASON FINALE Chef Roblé and Co., 10 p.m., Bravo Roblé caters a dinner party for erstwhile Saturday Night Live actress Rachel Dratch. Top Chef got Charlize Theron, just to let you know where this is on the famous chefs on TV pecking order.
