Those segments are like the scene of the Batmobile pulling up in front of the Police Headquarters in the 66 Batman. My 5 year old granddaughter noticed that on the 3rd or 4th episode we watched and now comments on it almost every time she sees the scene!Pete has grown on me. But he has no visible means of support. Where does he live? How does he pay his rent? With six packs?
I've also noticed that they use stock footage with the actors. The two stock footage sequences I've noticed are 1) when Petrocelli is about to put up a bogus sign on his windshield to get out of paying for parking and sees the meter maid, then pays and smiles at her; and 2) when his wife drops him off, he gets out forgetting to kiss her and she says, "Hey!" Through disc 4 I have seen those sequences at least twice, perhaps three times each.
The producers could never dream of DVDs and their original ten-year-old viewer binging on the show 40 years later. Otherwise, with weeks between each episode, it's doubtful too many viewers noticed
I have vague recollections of that scene with he and his wife. My set has shipped so maybe I'll push it to the front of the viewing queue...
