I don't think it's THAT unusual. Ex-writer & extra Conan O'Brien & that mediocre Jimmy Fallon both have talk shows. What irks me if that Seth's ego is so big that he has to do two shows at once; and both shows are live, too. Good luck working at 10am & midnight into your sleep routine. Time to leave, Seth. Everybody has to leave some time & you're no exception. *cue to clip of Seth clenching to the WU desk screaming while somebody off-camera is trying to pull him off it*
Also, Martin Short hosted a daytime talk show in 1999-00.
