This marked Farrah Fawcett's final appearance as a series regular. She returned for six guest appearances during seasons three and four.
When Kelly returns to the Police Academy, the establishing shot is the same one that opens the main credits.
This was Dirk Benedict's return to acting after two and half years of unemployment after beating prostate cancer. In his autobiography 'Confessions of a Kamikaze Cowboy' he remembers the three stars of the show being constantly followed around by assistants carrying large mirrors. This was to make sure no hair, makeup or clothing were ever out of place.
Sabrina's ex-husband, Bill Duncan, made only one other appearance on the show - in the earlier Target: Angels (1976).
Jill performs (questionable) chiropractics upon Bosley's back, at the end, and explains the chakras system and mentions Eastern philosophy. Other times, she was seen meditating and doing "OM" incantations. Being that the Townsend Agency's office was riddled with Buddha statues and busts galore, it is almost strange that they didn't write off Farrah as Jill going to the Himalayas to study para-sciences. Instead, the fictitious character---who didn't return for season 2---was dispatched to Europe, to participate the Grand Prix and other car races.
