Danny Trejo makes an appearance as an extra while Magnum is walking on the Santa Monica boardwalk. He passes in front of the camera shirtless eating an ice cream with his unmistakable chest tattoo.
Magnum sees a fiberglass cow on the sidewalk and laughs. At the time there was an art project in which artists could submit designs and, if accepted, painted their design on one of these cows, which were then placed on the sidewalks around Los Angesles. This was later imitated in other cities.
While on the moving sidewalk, Magnum's fellow passenger is looking at a man and Magnum tells her that the fellow looks a little old for her. She agrees and says that he's probably forty. Magnum breaks the fourth wall and looks at the camera. When this was being filmed, Tom Selleck was 41 years old. By this time, his age was first starting to show, making the dark dye applied to his hair and mustache increasingly obvious.
