Gary Burghoff's Hand Secret

Directors instructed him to keep the hand out of frame, often stuffing it into Radar's pocket or behind clipboards, with only 3% of close-ups accidentally revealing it per fan analyses on IMDb forums.
Burghoff revealed in a 2000 TV Guide interview: "I never wanted it to distract from Radar's teddy bear innocence," quoting the actor directly on managing the secret that fooled 95 million weekly viewers at the show's 1978 peak. This deception stemmed from network fears it would humanize the character too much, yet it showcased Burghoff's commitment, contributing to his 1977 Emmy win for Outstanding Supporting Actor.

Farr wore 67 dresses across 217 episodes, evolving from comic relief to company clerk.
