CBS programming executives reiterated their insistence Monday that the network's new medical drama L.A. Doctors is not some kind of joke. 'We are putting out a show called L.A. Doctors and are doing so with no humorous intent,' CBS president Leslie Moonves said. 'Each week, the triumphs and tribulations of a group of attractive young Los Angeles doctors will be sincerely dramatized on this not-a-joke program.' CBS is rolling out a high-profile promo campaign for L.A. Doctors featuring the slogan, 'We Are Honestly Not Kidding About This Show.'
