I think if you watch whatever the kids are watching, you'll find there are little references here and there to stuff the writers enjoy. These little moments, often non-sequiturs, tend to stick out, maybe because they seem a little out of place.
And I stumbled on a movie I would never have watched. But in reading the synopsis for it, I recognized a reference I had picked up as a small child from what was either the very late 1970s or maybe early 1980s. For less than a year (I'd imagine), everyone must have been making jokes about "Turkish prisons". The kind of thing that stand up comedias on Carson would have joked about, SNL, etc. And I overheard one of those jokes (or several), filed it away, and never figured it out.
Midnight Express (1978).
It's funny to me, there have been other such instances. Only took me 40-some years to solve.
It's a great story but if Moroder is your only interest in it, you're probably going to be disappointed (I like crime/thriller/escape movies myself). The song itself plays in an early scene and the rest of the movie is pretty bleak.
A Oh mumma make me happy, send me lots more cash
Don't worry, I saw the Midnight Express thirty-six times
And I know where to keep my stash
