 William Shatner (qv) had a severe case of flu during filming of  this episode. At one point he had to lift Sandra Smith (qv) in his  arms, carry her to a couch and put her on it: during the first take  he got as far as the couch and dropped her. Fortunately it was well  padded, and Smith bounced several times; according to Joan Winston,  who was visiting the set, Shatner looked down at Smith and said,  "You know I love you, baby, but youve got to lose about six inches  off that ass."
