When the Station 51 crew is watching Adam-12 (1968) Ambush (1971), firefighter Marco Lopez is sitting among them. Ironically, he would have actually seen himself as Marco Lopez, the actor who plays him, appeared as an uncredited Sheriff's Deputy in that exact episode of Adam 12.
If the guys watched the full episode of Adam-12 (1968), they would have also seen another familiar face as Ron Pinkard, who played series regular Dr. Morton, guest starred in this episode of Adam-12.
It's odd that anyone should be watching the Adam-12 TV series in this episode- Reed & Malloy showed up as characters in the Emergency! pilot movie, speaking to Nurse McCall at Rampart Hospital.
