Law & Order @ 10pm
A dry-cleaning store almost lost its shirt last year in court when it misplaced a pair of pants, and tonight's episode grabs that headline and puts its own twist to the tale. When the defense lawyer in the case is found brutally slain and the pants in question are the only thing stolen from her office, Green and Lupo follow a surprising trail of clues to a large retail chain with strict rules of conduct for their employees. One of the workers is Van Buren's old friend and mentor, but the man's eagerness to help crosses the line and threatens the case.
Reno 911 @ 10:30pm
After four seasons and a movie, you might be wondering if the Reno deputies have jumped the shark. They're actually wondering the same thing, which is why Dangle attempts to literally jump a tiny shark tank in this fifth-season opener. After the hilariously ill-fated stunt, they pick off where they left off last season, with Wiegel building the mystery of who fathered her child. Meanwhile, she's got no problem selling the newborn to the highest bidder.
Cashmere Mafia @ 10pm
Nothing's uncomplicated for the ladies tonight. Let's start with Caitlin: Although she's only cautiously exploring her flirtation with Alicia, a gossip blogger who saw them kissing at a dance club outs Caitlin to the world. Meanwhile, Juliet ponders taking the plunge with the old flame that the Mafia's "Revenge Sex Spreadsheet" selected for her; Mia locks horns with a male editor she hired for a relaunch of "Modern Man" magazine; and Katherine and Clayton slither into a messy office affair. Simplicity is overrated anyway, right?
Project Runway @ 10pm
It smelled like teen spirit last week when the remaining nine designers created prom outfits for a gaggle of teen-queen schoolgirls. The contest was nirvana for Victorya, whose bright gown took the crown. And then there was poor Kevin, whose "cheap and unflattering" garb warranted Heidi's heave-ho. He won't be around for tonight's decidedly hairy challenge, as the remaining seamsters fashion wardrobes based on various hairstyles. Expect the usual seamless fun: Circumstances make Christian want to "throw up," and it appears that a catty clash involves Sweet P. Sweeet!
