I learned I needed to re-watch "Space Seed" to remember what the hell that bit about Saavik changing her hairstyle was all about (referencing Khan convincing Lt. McGivers to change her hairstyle) besides showing off the fact that Kirstie Alley used to be rather attractive...
I also learned that the movie thankfully gave Khan a much better "final defeat" than the episode, where all his superior intellect and strength couldn't match a pipe to the face from Kirk.
Also, I learned it may have been too much to expect one of the guys to say "Fuckin' seatbelts, how do they work?"
Also, what the hell does Kirk say to Bones before Bones replies "What? You didn't like my act?" I've listened to Kirk's line like 10 times and all I can make out is what sounds like a mumbled "Physician."
