Conan O’Brien will unveil the name of his new late-night talk show on Wednesday, according to a Twitter post he made on Tuesday. “I was going to announce the name of my new show today, but my lawyers tell me The Return of Nanny McPhee is taken,” wrote O’Brien. “Tune in tomorrow.” Whatever it’s called, O’Brien’s new program will debut on TBS in November.
