CBS has given the go-ahead for a sitcom pilot starring former Saturday Night Live funnylady Cheri Oteri, Variety reports. In Loomis, Oteri — best known for her dead-on impersonations of Barbara Walters and Melissa Rivers — will play a small-town celeb who spends her leisure time trying to handle the challenges presented by her offbeat family and friends. Meanwhile, ABC has greenlit a comedy pilot starring Larry Sanders Show alum Jeffrey Tambor as the host of a TV cooking show.
