Do you think most of the IASIP audience got the Cuckoo's Nest references?

Sweet Dee has a Heart Attack features the amazing homage to One Flew Over the Cuckoo's Nest (a film Danny Devito was in).

Now, I'm sure all the peeps here knew that, loved it, understood everything.. but I'm wondering: did the general audience get it? The reference was probably 37 years old when this episode aired and is now over 50 years. So, do even newer viewers get it? Is it still a film almost everone has seen?

I loved it, one of my favorite books too.
