I think I need the XKCD explained website but for Farside comics.
I’ll give it a try, though not in as much detail as Randall goes into…
Finishing school was an institution primarily for young women to teach them the proper way for women to behave in society. It focuses on etiquette and the way to carry yourself to appear “proper” and “ladylike.” It was often seen as a way to help young women be more appealing as they search for a husband.
In this case, they are suggesting that before entering gorilla finishing school, gorillas would inappropriately walk fully upright, until they learn proper gorilla manners and posture.
Also young women had to learn to walk upright in a steady, feminine pose by carrying books on their head without them falling down.
Here’s the opposite since gorillas don’t walk upright.
