Forest Gump thought "life is like a box of chocolates, you never know what you're gonna get" because he was illiterate and couldn't read the little card.
I've always seen literal maps showing what's what. Sounds like maybe none of the Gumps could read. But even so, wouldn't you learn to tell the shapes apart? It shouldn't keep surprising you over and over.
I was mostly stuck on how that joke is older than most people on this site
I wouldn't be so sure about that. I'm pretty sure that Lemmy skews older to such a degree that most users are my side of 35 and the movie is "only" 30 years old 😁
