Whitney 8 p.m., Channel 7
NBC can be a little stubborn about holding onto its sitcoms, for good (“Parks and Recreation”) and for ill (“The Office,” season 9). Despite fairly crummy ratings, the network renewed “Whitney,” and it returns for season 2 on Wednesday night. It’s a mediocre half-hour, with lots of weak one-liners built on cliched gender humor about couples. Whitney Cummings and Chris D’Elia have great chemistry; too bad the writing doesn’t serve them better.
CSI: Crime Scene Investigation 10 p.m., Channel 4
Twist! The show is turning back — way back — to the days of Warrick Brown. Warrick was played by Gary Dourdan (pictured), the actor whose arrests have led to regular appearances on TMZ. Warrick died at the start of season 9; tonight, the team investigates the death of a reverend who was killed at Warrick’s grave site. The ad makes it seem as though Warrick’s fingerprints were found on the scene, but, yeah, that could be a false come-on.
