Jon & Ponch's dates were both former Playboy July playmates. Jon's date Lynn Theel was Miss July 1975 (as Lynn Schiller), and Ponch's date Sondra Theodore was Miss July 1977. It was Theel's first TV appearance, Theodore's second, and neither actress appeared again on the show.
After asking Getraer for a transfer, Poncherello tells Jon he was commissioned onto the CHP in 1975.
While watching the film of Poncherello falling off the jet ski, he tells Jon that he will get him for showing the film, and mentions it may not be until Jon makes Lieutenant or retires. This was a foreshadowing of Jon being promoted. About 21 years later in CHiPs '99 (1998) Jon had made Captain by the time Poncherello returned to the CHP.
