During more than three decades of movie making and theatre, John Ratzenberger has enjoyed success as a screenwriter, director, producer and multi Emmy-nominated actor. He is also an accomplished entrepreneur and philanthropist.

John’s career began in earnest in the early 1970s, when he formed the improvisational theatre duo “Sal’s Meat Market,” which performed to standing-room-only crowds throughout Europe for 634 straight performances. To help pay the bills, John also worked as a house framer, archery instructor and deck hand on a fishing boat. Learning a few trades allowed him to pursue his dream of acting.

In 1982, John accepted a writing assignment for CBS in Los Angeles. On the day he was scheduled to return to London, he auditioned for a role on the upcoming Cheers. At the time of his audition, the character of the postman did not exist. As he walked out of the audition, he turned and asked the creators in the room “Do you have a bar know-it-all?” They didn’t know what that was, so John gave them five minutes of improv, demonstrating exactly what it meant with the perfect Boston accent. They loved what they saw and Cliff Clavin was born.

In the history of television, only a handful of series have achieved the worldwide success of Cheers, on which John portrayed Cliff for the show’s entire 11-year run. To this day, thanks to daily syndication, Cliff continues as one of America’s most beloved characters.
