Just started watching Adam 12 on Netflix. Haven’t seen it since I was a kid, and have been re-living my childhood! I first noticed Biff’s in Season 1 Episode 6, Log 161 “And You Want Me To Get Married”. I missed the exact time stamp, but it was within a few seconds of 16:30. The guys walk out the door door, talking about how great the food is, and of course Malloy talks about how pretty the waitresses are. Wish I had found this site a few years ago when this was all new. I miss everything.
