Whaddya mean, “all three verses”? There’s at least seven, but most people have too much of a life to be able to memorise “Lo, star-led chieftains…” or “Child, for us sinners…”
I used to be able to recite “Hiawatha’s Wedding Feast”, but this is one of those use-it-or-lose-it propositions and it’s faded beyond recall now. On the other hand, I think I could still quote Newbolt’s “Songs of the Fleet” chapter and verse.
Most of the exams for my first degree were of the kind where the lecturer reveals the question about a week or a few days beforehand so that you can go study the relevant parts of the subject. Invariably I’d do that, sit me down and write out a fantastic essay (I checked with the lecturer what grade it would ‘theoretically’ get) and then just memorised the damn thing. Did that for many, many exams and it relives the stress of the whole thing.
On paper routes, sorry but my dog can beat that. I had a paper round for about 3 years and often took my dog with me. The dog would invariably trot on ahead and wait at the gate/door of the next house depending on whether the people there were dog-friendly or not. About 8 years later I would happen to walk down some of the same streets along with the pooch and she’d faithfully stop at all the appropriate gates/doors. 
I can remember my secondary school class register (for US dopers - JHS/HS home room roll call). I am 44 and last heard it in 1980 yet I can reel off all 31 names alphabetically in under 10 seconds!!!
I can also reel off the complete periodic table from Hydrogen up to Rutherfordium - yup I am aware there are newer elements after Rf. I’ll have to work on that.
When I was eleven years old, my often-absent father took me to his mother’s house. At one point, I was standing in the living room, facing the fireplace, and I had a perfectly vivid memory of sitting on a couch (where I was standing, although there was no couch there), facing the fireplace, with someone sitting next to me (although I couldn’t tell who it was)- and then a bird flew down the chimney and circled around the room.
I told my grandmother about it, and she said that happened when I was about three months old, which was the last time I’d been in that house. The person sitting next to me was my cousin Micah, who is almost exactly the same age I am. So, yeah, a vivid memory from when I was three months old.
I can also still say the Pledge of Allegiance in Latin, which I haven’t studied in over twenty years. However, I’m completely unable to remember if I closed my garage door when I left for work this morning.
I’ve posted this here before, but when I was in 5th grade I got Castlevania 2: Simon’s Quest for a birthday present. At the time it was the most difficult game I’d played in terms of time it took to finish. Instead of memory cards back then it was codes you had to remember to start back in the same place with the same inventory. My mom always threw away the paper we wrote them down on, so I took to memorizing them. The code that starts you right at the end before you fight Dracula, along with enough holy water and garlic to whomp on him is MKGS WVCW T3KU VYZC.
For whatever reason my brain has assigned this particular piece of information Top Priority Status. I’m 28 years old so I’ve retained that for damned near 20 years.
At work, I own well over 750 individual topics on various thingers in at least two product incarnations for three different audiences, and I have a good working knowledge of who else owns what and how their content tends to impinge on my own. So if you toss me a subject or a title, it takes me only a minute to ID it as mine or Coworker A or B’s.
I memorized the second half of a Yeats poem in… middle school… which would make it nearly 15 years (!), and still remember it. The poem was ‘Of Unworthy Praise’, which I love so much that I’ve been severely tempted to get the last two lines tattooed somewhere.
I can still remember minutiae such as the phone number of the house I grew up in, 3x3 magic square, the Prodigy ID I used when I was 13, and so on. Unfortunately, I often forget to eat lunch even when it’s by my elbow…
Airport codes. The people I work with have done a LOT of traveling that I’ve had to set up - I know just about every single airport code. I’m not proud of this - I would have hoped my brain would have retained something USEFUL. :rolleyes:
This is not as impressive as the rest, but oh well. When I was in college, one night I went to a club in San Francisco with a fake ID. There I met a nice guy who bought me several long island ice teas. Well, I got so drunk I threw up in a trash can next to the dance floor and got up on the stage and tried to seduce a nice young woman and did more humiliating stuff, which I have no memories of at all. At the end of the night, when my friends were trying to get my uber-drunk and delirious ass home, we went to the coat check to get my jacket. I had lost the ticket - presumably in the bathroom as I had shoved the ticket into my dress for safekeeping. Despite the fact I was completely wasted, I remembered the ticket number for my jacket. I had looked at it exactly once that night, when we arrived.
I can tell you the location of any house/apt in Platteville WI. If you tell me the street adress, I can tell you what side of the road it is on and the cross roads on either side of it.
How does one obtain such a skill? I delivered pizza for almost 5 yrs in college.
Although I have no use for it, can recite a Robert Frost poem that I memorized in the 8th grade. I really need to clean out the brain sludge.
I have to give Percocet the credit here, but after some recent oral surgery, I took a pill and had a long waking dream in which I toured the house where I grew up and looked at/touched every inch of the house and the contents in it and remembered things I haven’t remembered since I was too short to see above the kitchen counter. Does that count?
p.s. it was one of the most wonderful things I’ve ever experienced. I woke up crying. But that could’ve been the drugs, too… 
I can recite the first two of T. S. Eliot’s Four Quartets- Burnt Norton and East Coker. I got stuck halfway through the third one. It’s a great way to turn off your brain, listening to yourself metally recite poetry.
Doesn’t impress a whole bunch of people.
I remember a lot of random facts, especially anything science or history related. My family keeps suggesting I try out for Jeopardy; maybe I will one of these days. After I read a novel I generally remember enough to give a detailed summary for several years afterwards. This is useful when authors are slow to release new books. (I’m looking at you, George RR Martin!)
I took French for a couple years, back in the late '50s, and I was only an average student. After that time, I studied a few other languages and basically forgot any of the French I had learned. In 1999, about 40 years later, I was planning my first trip to Paris. I got a French textbook, tried to see if I could remember anything, and gave up, finding it much too difficult. But when I actually got to Paris, I found myself conversing fluently with people, using words and verb tenses I hadn’t thought of in 40 years.
I used to be able to identify any font, just by looking at a couple characters (sometimes only 1). And if you gave me the name of a font and a character, I could draw it from memory. Of course, that was in the days before desktop publishing, when there were only about 6000 fonts in existence.
I sometimes have dreams of entire long works of music, like a symphony or opera, as if I’m actually hearing every note or word. There’s nothing visual in these dreams, only the music.
On the weekend I met up with a friend of mine and he recalled a feat of mine that amazed him however it was really just a fluke. We both went to school and earned our licences in Canberra and when we were living together in Sydney went to the registry together to get NSW licences. 30 years later I was with Graeme while he was renting some tools and the guy behind the counter asked him for his licence number. I correctly quoted the 4 digits and 2 letters. Graeme had no recollection of us picking up our original licences together and was dumbfounded when he pulled it out and discovered I was correct.
