Aww, but I really like both duos.
Also, now that we finished, I got to take a glimpse into the source material myself and see what I can find.
My first original find back in the days had been the von Recklinghausen doctors which might or might not be another coincidence:
Heinrich von Recklinghausen - Wikipedia - his dad is referenced there, too
(As a sidenote: Almost bursting into laughter because you just hear the name Morbus Recklinghausen in a diagnostic lesson with the other teachers/students not knowing what's going on was quite the moment)
Also, from #13:
World of Ruin - oh my, FF6 again. The world map in the second half is called World of Ruin and I'd totally make that joke in my recaps

You're my only hope - Star Wars, Princess Leia's famous quote "Help me, Obi-Wan Kenobi, you're my only hope"
God is dead - Quote from philosopher Friedrich Nietzsche
from #12
Rock of Ages - a movie, a rock festival and also a reference to the Rock of Cashel (which is referenced as the "stone of destiny" in other fiction)
