Logarithms, naming the parts of a sentence, your high school locker combination.
We spend at least nine years going to school, with teachers doing their best to feed us information that we'll more than likely never use again. I don't remember much of what I learned in school, except for a song about how many days are in each month.
"Thirty days has September, April, June and November. All the rest have thirty one, except February."
Redditor u/Org_ChemistVir asked people, "What is the most useless thing you still have memorized?" and people shared the useless information that they've learned over the years through school, or just in life.
9. Great for people who actually live in Mississippi
"M-I-s-s-I-s-s-I-p-p-i
I have never had to spell Mississippi as an adult."
8. I actually love that they memorized this
"'What rules? We didn't see any rules, did we Charlie?"
'Wrong, sir! Wrong! Under section 37B of the contract signed by him, it states quite clearly that all offers shall become null and void, if, and you can read it for yourself in this photo static copy, 'I, the undersigned, shall forfeit all rights, privileges, and licenses, herein and herein contained et cetera, et cetera. Fax mentis incendium gloria cultum, et cetera et cetera. Memo bis punitor delicatum!' It's all there, black and white, clear as crystal! You stole fizzy lifting drinks! You bumped into the ceiling, which now has to be washed, and sterilized, so you get NOTHING! YOU LOSE! GOOD DAY, SIR!'"
6. I would really appreciate a lesson in taxes
"When growing up, my dad had an experiment to teach me something that I would remember simply by repeatedly asking me afterwards. REPEATEDLY.
Because of this, I learned the 4 moons around Jupiter. Not how to do taxes, not the correct way to professionally network but Io, Callisto, Ganymede and Europa."
4. I stopped locking my locker because I could never remember the combination
"My locker combination in 8th grade. That was a long time ago!"
3. A little jealous of this skill
"I can recite the entire soliloquy from Hamlet.
Whenever someone around me for some reason says 'to be, or not to be,' my wife instantly tries to drag me away before I can start. I do the intonation and flailing hand gestures too. It gets ugly."
2. It might be the most simple Seuss book
"The entire book One Fish Two Fish Red Fish Blue Fish"
