    Bad Teacher 9:30 p.m., CBS

    I’ve developed an irrational and potentially career-dinging affection for this show. It’s not very good, overall, but as the bad — and fake — teacher looking for a rich single father at Richard Nixon Middle School, Ari Graynor is too much fun. She makes the absurdity of the premise easy to accept, and her rapport with the unpopular kids — she’s selfish but also an underdog — adds some heart to all the crass humor.

    The iHeartRadio Music Awards 8 p.m., NBC


    Sigh, another new awards show, only weeks before the Billboard Awards. This back-pat-fest is linked to the iHeartRadio Music Festival and the iHeartRadio radio network, and the winners are based on iHeartRadio listener choices and radio performance data. In other words, this is all just another excuse to get stars on the air and make youHeart iHeart, which iDon’t. Scheduled performers include Drake, Pharrell, Blake Shelton, Kendrick Lamar, Pitbull, Shakira (pictured), Luke Bryan, Arcade Fire, and Ed Sheeran.
