Michael Weatherly On 'The Cosby Show': How 'NCIS' Actor Got His Start (VIDEO)

Michael Weatherly is gearing up to celebrate the 200th episode of "NCIS," which he stars on as Special Agent Tony DiNozzo. And while Weatherly has enjoyed quite a run on the military procedural, he told "CBS This Morning" (weekdays, 7 a.m. on CBS) about his less-than-auspicious start in show business, which included a one-episode fill-in spot as Theo's roommate on "The Cosby Show."

Weatherly told the story of his early days as an actor and how he fell into the "Cosby" cameo. "I had nothing on my resume except stuff I made up, it was all completely fictional," he said, joking that lying was much easier in the days before IMDB and Google. "My manager represented a guy who played Theo's roommate, and he booked a movie with John Turturro and wasn't available. But I was the same size as him, so she called me and said, 'Get out to Queens, you're gonna meet Bill Cosby and if he signs off on you, you're gonna be working this afternoon, they're taping. And I met him and he was in a track suit smoking a cigar, he had a rubber chicken nailed to his dressing room door. I did okay, but they never invited me back ... it was a one shot deal."

Fortunately for Weatherly, his "NCIS" gig has lasted quite a bit longer.

The 200th episode of "NCIS" airs Tuesday, Feb. 7 at 8 p.m. EST on CBS.
