How about in real life?
Good one!
Another was “The Homecoming Queen’s Got a Gun”.
He was trying to hit his wife with a leg of lamb, and missed.
Guess my parents were fairly progressive? Or we lived in a more progressive area? But I also grew up in the 50s, and we always called them Brazil nuts. I think I was in my teens before I first heard the other name.
A real life Lamb to the Slaughter?
Sure, if you think Mayberry is “real life”.
By your examples I guess you would not like The Kinks “Art Lover” either.
Following Darren_Garrison’s example I regret that neither Azhdarchidae nor Nyctosauridae will fly no more.
Yep. Came here to post that. 
Ringo said he won’t sing "You’re sixteen, you’re beautiful " like he used to.
Rock stars with underage girlfriends, e.g. Jimmy Page, David Bowie.
Smoking just about anywhere.
Yeah. Smoking in offices, planes, hospital waiting rooms, etc.
Just what I was thinking.
Damn, Carrie Fisher was beautiful!
I’m pretty turned off by Sweet Caroline, and around here that gets played all the time, and then people start shouting and pumping there arms during the song like “Yeah, go old man, touch that 11 year old girl”. And I happened to love her myself when she was 11 and I was 12 you slimy bastard. Anyway this is a complete digression because that stupid song is very popular and flying right now. Nevermind.
Neil Diamond may have been inspired by an eleven-year-old Caroline Kennedy but it’s not necessarily about her; in 2014, he said it was about his wife at the time.
Well of course that’s what he’s gonna say. But he could have just said it was about his wife right from the beginning. In what way did my should have been 11 year old girl friend remind him of his wife?
I grew up in the '50s, and always called them Brazil nuts. I didn’t hear the other name till I was an adult.
And how about corporal punishment by teachers?
Ostriches. And penguins. But I guess they wouldn’t fly back then, either.
Drinking and driving. My recollection is that in the 60s (and earlier, I assume) no one thought much of knocking back a few drinks and driving home afterward.
Has the emotional support animal window closed?
