#2: Don Knotts Was Nervous About Three’s Company Until the Audience Erupted
According to the biography Andy and Don by Daniel de Visé, Don Knotts was extremely nervous on his first day on the Three’s Company set. He had never worked on a three-camera sitcom before, since The Andy Griffith Show used a single-camera format.

Knotts also worried about fitting in, later admitting, “They were all much younger than me… and they were all good.” His fears disappeared instantly when he walked on set and the studio audience gave him a ten-minute standing ovation, warmly welcoming him to the show.
