I remember that well. Tucker the Jerk kept nudging Jon to "say something funny," "say something funny," and Jon said "I'm not your monkey." As I remember Crossfire was cancelled shortly after.
My sister just retired from Santa Monica Hospital (now part of the UCLA chain), and in the early days she said they'd have patients smoking in their rooms....with oxygen tanks right there. She also said it was a real pain having to play musical beds with all the patients who didn't want to be in a room with a smoker. Today that sounds insane.
When I was in the hospital (St. John's in Santa Monica) getting my tonsils out and minor ear surgery in the early 60s, my roommate was a Thalidomide victim. She only had stumps for both arms and legs, but I was so impressed by how well she could color by holding the crayon between her shoulder and cheek (we shared coloring books).
Smoking was always pretty popular, but the tobacco companies lobbied the government to include cigarettes in the rations that G.I.s had in WWII. That hooked an entire generation.
