TV For March 31: American Idol, Mobbed, Grey's Anatomy

American Idol, 8 p.m., Fox

Honestly, I can’t even remember what happened last night. So I’m not making any predictions. Just remember: they already used the Save. Oh, and Miss Fantasia is in the house.

Mobbed, 9 p.m., Fox

I admit it. I am a sucker for those flash mob videos. Even the ones that aren’t spontaneous, like that Oprah Black-Eyed Peas one. So I am putting aside my dislike for Howie Mandel in order to check out this new show, in which people use a flash mob to tell someone something – like, a marriage proposal for example. I am so there.

Grey’s Anatomy, 9 p.m., ABC

Shark-jumping or innovative? Grey’s goes Glee tonight. Whatev.
