Classic episode with drugs, prostitution, etc., in all its grimy glory, but seriously, In what world can a complete stranger burst into someone's apartment and say, "Hey, I'm a friend of your druggie friend, can I come in?" And the person lets them in and the visitor says, "Hey, can I use your tools to shoot up? I have my own stuff, I just need your kit." And the accommodating apartment dweller says, "Sure, go right ahead in the bedroom, help yourself."
Who does that? In the 70s was that done? I am not sure but this is the second post-Gilligan's Island show I have scene that puts Tina Louise in a ridiculously crafted scene, the other one coming shortly after this particular show: a Dallas episode where she agrees to jump off a roof because a crook said to.
