Memorizing the presidents is on my to-do list as well, BigDan—and neither I can visualize all of their faces. This is what I plan to do. First I’ll make some simple flash cards. The common way to go about it would be like this:
Question side: 1st U.S. President. 1789-1797. No Party
Answer side: George Washington
But gee, that gives us no vivid images! So instead I’ll make cards like this, where I write a clear and readable sentence with trivial information as a cloze test, and then having the “pudding” in the parenthesis.
Question side: The Commander-Chief flag, a blue banner with thirteen stars was _____ _____'s personal flag which accompanied him wherever he went whether in camp or on a battlefield (He was the first president of America. He helped to establish the federal government and aspired to create a free, democratic and united country. His term in office as the American president was from 1789 until 1797)

Answer side: George Washington
I’ll make a stack of such cards, giving me a vignette for each president. After I’m done with that I’ll make a journey with enough loci for all the presidents. That’d go something like this:
Loci 1. A washing board
Loci 2. Adam (from the Garden of Eden)
Loci 3. T. J. Hooker
Loci 4. Mad-Eye Moody (he’s mad cuz he didn’t make the third prez)
Loci 5. Marilyn Monroe
Loci 6. Dr. Quincy
Loci 7. Johnny Cash (he’s goin’ to Jackson!)
Loci 8. A van goin’ burrr
Loci 9. Harrison Ford
Loci 10. Tyler
Loci 11. People are so happy to get a new prez, they’re doing the polka
Loci 12. Zapp
Loci 13. A mill that shouldn’t be filled more
Loci 14. Pierce Brosnan
Loci 15. A buck
Loci 16. A Lincoln
Loci 17. A.J. from the Sopranos
Loci 18. Odysseus
Loci 19. Haye
Loci 20. Garfield
Loci 21. King Arthur lighting up a Chesterfield
Loci 22. Cleveland
Loci 23. A breast holder (bra)
Loci 24. Cleveland throwing away the bra
Loci 25. A suit from McKinsey, huffy cuz the bra was thrown away
Loci 26. A teddy bear
Loci 27. A taffy
Loci 28. A wood
Loci 29. Warren G
Loci 30. Kool-Aid
Loci 31. A hoover
Loci 32. A rooster
These are just associations, or mems if you will, that I came up with on the fly. I think it’s easier to remember two things that interact in each loci, and to not get confused about the order what’s at the left side of the loci is always what comes first. Then it’d go something like this:
Loci 1. A washing board hits Adam in the head
Loci 2. T.J. Hooker pushes Mad-Eye Moody away
Loci 3. Marilyn Monroe seduces Dr. Quincy
Loci 4. Johnny Cash kicks the van, which then goes burr
Loci 5. Harrison Ford says Tyler can’t rap
Loci 6. They’re doing the polka, which makes Zapp smile
Loci 7. A mill that shouldn’t get filled more gets filled by Pierce Brosnan
Loci 8. A buck dents a Lincoln
Loci 9. A.J. spits on Odysseus
Loci 10. Haye picks up Garfield
Loci 11. King Arthur lights up a Chesterfield, asking if Cleveland would like some
Loci 12. A bra falls down and Cleveland goes around it and picks it up
Loci 13. A suit from McKinsey kicks a teddy bear
Loci 14. A humongous taffy melts on the wood
Loci 15. Warren G drinks the Kool-Aid
Loci 16. A hoover tries vacuuming a rooster
You could make a story as to why all of this is happening. The more bizarre, the better. Let’s say you were naming all the presidents, but forgot the 19th, Rutherford B. Hayes. But you remember the 20th, Garfield. So when thinking what happened to Garfield, one would get a vivid image of Hayes - and there you have them all!
